Abstract :
A novel, space vector modulated, zero-voltage-transition, three-phase boost rectifier/voltage source inverter with coupled inductors in the auxiliary circuit is proposed. The ZVT operation of the power converter is accomplished by the use of a low power rating auxiliary circuit. The ZCS operation in auxiliary switches is also achieved with a new control scheme
