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.
