Your weekly digest of news, analysis and perspective on the global power electronics industry.

Editor's Note

Maurizio Di Paolo Emilio – Editor-in-Chief

The AC/DC power supply, also known as AC/DC converter, is an essential component of many electronic applications, including consumer electronics, industrial, robotics, medical, and military ones. In this issue, we analyze the main issues engineers face when designing an AC/DC power supply PCB, such as signal integrity, power line integrity, electromagnetic interference, output voltage stability, and thermal management. Moreover, we look at a full bridge based VHFI for electrosurgery. A 390 kHz output frequency experimental setup based on a 300 W gallium nitride high electron mobility transistor (GaN HEMT) device has been developed to test the viability of the VHFI. Other topics are SiC-based solar inverters, integration architectures, and EV batteries. The automotive industry is off to the races in vehicle electrification and automation; click here for the full agenda and free registration of our Automotive Forum. Don't miss the latest episode of the powerUP podcast about motor control design. Enjoy!

Highlights

Guidelines for AC/DC Power Supply PCB Design

The current trend towards ever lower power supply voltages, small footprint, low weight, and high efficiency, requires an accurate design of the power supply circuit, performed starting from the PCB.

Electrosurgery: Using a GaN-based VHF AC Power Supply

The proposed VHFI achieves a total harmonic distortion (THD) of less than 2.5% and a quick response time in both blend cutting and coagulation mode, thus validating the design’s viability and confirming its capacity to support different load values in several clinical modes.

SiC-Based Solar Inverter for Renewables Industry

Navitas Semiconductor and KATEK Group have announced that KATEK’s coolcept fleX series of Steca solar inverters have embraced new GeneSiC power semiconductors for enhanced efficiency…
