Scientists in the Emirates have conceived a new space vector pulse width modulation method that reportedly reduces switching losses and increase efficiency in three-phase photovoltaic inverters. The ...

The UCC28950 phase-shifted full-bridge PWM controller with synchronous MOSFET control outputs and light load power management can achieve efficiencies above 90% from light load to full load ...

EPC has come up with a 3-phase BLDC motor drive inverter reference design which operates from an input supply voltage range of 14 V to 60 V and delivers up to 60A output current. This voltage range ...

EPC has introduced an evaluation board implementing a 40Arms (60A peak) three-phase inverter that will run from 30V to 130V. Called EPC91200, it is “suitable for 80 and 110V battery systems commonly ...

Allegro Microsystems developed and launched the A4938 last 2010. This device is a three-phase brushless DC (BLDC) motor pre-driver that supplies direct, high-current gate drive of an all N-channel ...

This paper presents the system concepts and describes the circuit implementation of several key features. The increasing use of high-current brushless dc (BLDC) three-phase motors puts stringent ...

Almost all off line switching power supplies over several kilowatts of output power use a three phase bridge rectifier. Typically, it comprises a six diode bridge and a DC bus filter capacitor. A ...
