Advanced technologies to improve efficiency:

Utilizing advanced technologies for expanding product portfolio and improve efficiency are among the topmost agenda for tech companies. Infineon Technology utilizes the advanced neutral-point-clamped (ANPC) topology for its EasyPACK 2B, a hybrid silicon-carbide (SiC) and IGBT power module.

This module belongs to the 1200-V family. Improving the sweet-spot losses of the TRENCHSTOP IGBT4 and CoolSiC MOSFET chipsets, this new module offers enhanced power density and switching frequency of up to 48 kHz. It is suitable for energy storage applications and 1500-V photovoltaic storage applications. Infineon states that this topology offers a system efficiency of nearly 99%. EasyPACK 2B weighs less than other counterparts with only silicon components. Moreover, SiC enables fewer losses than those with silicon.

This leads to less dissipation of heat and shrinkage of heat sink. This, in turn, attributes to less inverter housings and cost savings. As compared to other five-level topologies, its three-level topology offers less complexity in design of inverter. As per the company, its negative-temperature-coefficient (NTC) sensor helps in easing up the monitoring of the device and the PressFIT technology lowers down the assembly time to install the device.

Converters for wearable electronics and IoT:

New product launches to enhance the product portfolio and offer new solutions is one of the major strategies adopted by market players. Ricoh Electronic Devices Co. Ltd.

launched two-buck dc-dc converters for applications in wearable electronics and internet of things (IoT). The RP516 and RP517 have been launched for solutions requiring extended battery life, less mounting area, and reduced weight on high-density boards. As wearable technology and IoT devices in today’s applications mostly operate in sleep mode, the quiescent current is crucial for the consumption of power.

The new converters have been optimized for extended battery life along with applications that need low supply voltage, ranging from 0.3 to 1.2 V.

According to the company, the new kind of power supply is designed for assisting the new generation of low-power MCUs, GPS/GNSS processors/receivers, and other ICs needed in IoT applications. The operation of dc-dc converters is carried out in VFM mode.

The efficiency of light loads reaches at 75%. According to the company, the efficiency performance of 75% can be reached at 0.01-mA output current. Moreover, the synchronous rectification is offered along with the integration of low- and high-side MOSFET driver transistors. An auto-discharge function is enabled for rapid discharge of the output capacitor as the chip is disabled by CE pin.

Lightweight & portable converter for aerospace applications:

Offering portable and lightweight generator for aerospace and operations at remote locations would offer many solutions related to ease in use and operational feasibility. Digicom Electronics, Inc., an Electronics Manufacturing Services (EMS) firm, offers its new 400 Hz power converter.

A portable and lightweight converter, GENO 400 Hz Digicom Power Converter Model 779 operates on 100 VAC–250 VAC, 50 Hz, 60 Hz, and 400 Hz frequencies along with single, two, and three-phase inputs. In addition, it has the ability to convert the power to 120 VAC 60 Hz output. The new design is ideal for applications in the aerospace, construction, military, and others that involve activity in remote locations where there is an unavailability of the standard power grid.

The default power to the aircraft and ground support equipment at maintenance facilities can be offered. As diesel power generators are the crucial equipment used in remote areas. Those generators are designed to operate on 110-120 VAC, 50 Hz. This presents an ideal option for seamless operation for power conversion. The harmonic distortion of the converter is 5% and enables short-circuit protection.

It contains four outlets with access ON/OFF switches, LED status indicators, and two internal cooling fans with vents equipped with an air filter. This makes the GENO easy to use and maintain.

The best places to spot bald eagles in Missouri this winter

The best places to spot bald eagles in Missouri this winter

ST. LOUIS, Mo. – Since 1782 the majestic bald eagle has been the national bird of the United States. They were on the verge of extinction when the federal government declared them endangered in 1978.

Now, the species has made a remarkable comeback, and spotting them isn’t as rare as it was decades ago. The state of Missouri is sort of a magnet for the birds as they move south for the winter, looking for open water to fish.

There are more than 175 active eagle nests in Missouri. Typically there are more than 2,000 bald eagles spotted during the winter.

Spotting the birds often depends on the weather. Temperatures up north must be cold enough to push the eagles southward. But if a major cold spell freezes most lakes and wetlands, the birds will migrate south.

You can see the birds along the Mississippi River. They are often seen in trees along the banks and near the locks that control the flow of the water.

The Missouri Department of Conservation reports that you can see the eagles in the Kansas City and St. Joseph areas along the Missouri River. They often perch in tall trees looking for prey.

Here are some of the best places to find bald eagles in Missouri:

  • Old Chain of Rocks Bridge south of I-270, off of Riverview Drive, St. Louis
  • Audubon Center at Riverlands east of West Alton
  • Lake of the Ozarks at Bagnell Dam Access, east of Bagnell
  • Eagle Bluffs Conservation Area on Route K, southwest of Columbia
  • Lock & Dam 24 at Clarksville
  • Lock & Dam 25 east of Winfield
  • Mingo National Wildlife Refuge northwest of Puxico
  • Schell-Osage Conservation Area north of El Dorado Springs
  • Smithville Lake north of Kansas City
  • Loess Bluffs National Wildlife Refuge south of Mound City
  • Swan Lake National Wildlife Refuge south of Sumner
  • Table Rock Lake and Shepherd of the Hills Fish Hatchery southwest of Branson
  • Truman Reservoir west of Warsaw

66-year-old who disappeared before trial for sex crimes found dead

ST. LOUIS COUNTY, Mo. – A 66-year-old local man who was reported missing on the morning he was due in court to stand trial for numerous sex crimes has been found dead.

Michael Taber had been staying at an apartment in the 1900 block of Lemay Ferry Road. He went missing around 2 a.m. on Monday, Nov. 29. According to the St Louis County Police Department, Taber left his cellphone and a suicide note behind, as well as an ankle monitor.

Court records indicate Taber was ordered to wear an ankle monitor while awaiting trial in St. Louis City for one count of second-degree statutory rape, two counts of second-degree child molestation, one count of second-degree rape, two counts of second-degree aggravated sexual abuse, one count of second-degree statutory sodomy, and one count of unlawful use of a weapon.

St. Louis County Police sent out a tweet Monday afternoon saying Taber had been located. A department spokesperson said Taber was found dead due to a probable self-inflicted gunshot wound.

Police did not say where Taber’s body was discovered.

Parade of planets visible in the night sky this week

ST. LOUIS – There will be a parade of planets this month. December 6-10 you will be able to see three planets and then on December 12 you will be able to see 5. There will be a crescent moon earlier in the month which will provide less moonlight, making it easier to see the planets.

The Missouri Department of Conservation shared this timeline for planet viewing:

  • On December 6th, the crescent moon will appear near Venus within 3 degrees in the early evening sky. Venus is the brightest planet.
  • On December 7th, the crescent moon and Saturn are about 5 degrees apart. Saturn is a fainter planet with a gold color. If conditions are right, you can see its rings with a telescope during twilight, and may even see its largest moon, Titan,
  • On December 8th, the moon approaches close to Jupiter, our largest planet. With clear conditions and a telescope, you may be able to see its four largest moons.
  • On December 10th, look for the moon, Jupiter, and Saturn forming a nice row in the sky.

The St. Louis Astronomy Facebook page says the best time to observe 5 planets together will be after sunset on December 12. Venus, Saturn, Jupiter, and the moon will be visible to the naked eye. You will need a pair of binoculars or a small telescope to see Neptune, Uranus, Ceres (a dwarf planet), and Pallas (a large asteroid).
