Texas Instruments introduced two new device families that help reduce size and weight in motor drive applications. When used together, DRV832x brushless DC (BLDC) gate drivers and CSD88584/99 NexFET™ Power Blocks require as little as 511 mm2, half the board space of competing solutions. The DRV832x BLDC gate drivers feature a smart gate-drive architecture that […]

D3 Semi marks its […]
Half-bridge modules carry 1.2-kV SiC MOSFETs
Higher efficiency, increased power density, smaller footprints and reduced system costs: these are the main advantages of transistors based on silicon carbide (SiC). Infineon Technologies AG is starting volume production for the EASY 1B, the first full-SiC module announced during PCIM 2016. On the occasion of this year’s PCIM in Nuremberg, the company is showcasing […]
Power MOSFETs with fast-recovery diode target ZVS converter apps
The latest MDmesh DK5 power MOSFETs from STMicroelectronics are Very High-Voltage (VHV) super-junction transistors with the extra advantage of a fast-recovery diode. This helps designers maximize the efficiency of various power-conversion topologies including LLC resonant converters with Zero-Voltage Switching (ZVS). As super-junction MOSFETs, the new devices — in voltage ratings from 950V to 1050V — […]
Littelfuse and Monolith Semiconductor debut 1200 V Silicon Carbide (SiC) Schottky diodes at PCIM
Littelfuse, Inc. and Monolith Semiconductor, Inc. introduced the first commercially available silicon carbide devices developed through their partnership: the GEN2 Series of 1200 V Silicon Carbide (SiC) Schottky Diodes. Visitors to the Littelfuse booth (Hall 7, Booth 335) at the PCIM (Power Conversion and Intelligent Motion) Europe 2017 Exhibition can talk to technical experts about […]
N-channel MOSFETs sport super-low on resistance
Toshiba America Electronic Components, Inc. (TAEC)* has expanded its U-MOS IX-H Series of low-voltage N-channel power MOSFETs with the addition of new 40V and 45V products. Delivering high-speed performance and industry-leading[1] low on-resistance, the new MOSFETs are designed for industrial and consumer applications, including high-efficiency DC-DC converters, high-efficiency AC-DC converters, power supplies, and motor drives. The new […]
Reference design covers 3-kW continuous current-mode bridgeless Totem Pole PFC in GaN
Achieving efficiencies greater than 98% in conventional Power Factor Correction (PFC) circuits is challenging. The major hurdle is fixed diode bridge losses. An option to overcome this is to use silicon MOSFETs in place of the diodes to achieve efficiencies of 99% or more. However, this BTPPFC approach suffers from poor reverse recovery performance, is […]
