Zero-voltage-transition (ZVT) 3-phase PWM voltage link converters
(United States Patent and Trademark Office, 1996-11-12)
An improved zero voltage transition (ZVT) pulse width modulation (PWM) link converter is provided which introduces a space vector modulation scheme and an auxiliary circuit which includes a commutation power supply or ...
Soft-switching PWM converters
(United States Patent and Trademark Office, 1995-08-15)
A full-bridge zero-voltage-switching pulse-width-modulated converter employs a saturable reactor in place of the linear inductor in order to reduce current stress on the active switches, reduce voltage stress on the rectifier ...
Soft switched three-phase boost rectifiers and voltage source inverters
(United States Patent and Trademark Office, 1997-05-27)
A boost rectifier is provided with an ultra high speed diode in its direct current rail to reduce diode reverse recovery loss with or without implementing a soft switching technique. Full zero-voltage-transition (ZVT) as ...
