Abstract :
This paper proposes two arbitrary zero-placement (discontinuous) PWM strategies for DC-AC three-phase voltage-source-inversion and three-phase AC-DC voltage-source-rectification respectively. They are based on the general space vector modulation approach derived from matrix converter theory. The two PWM strategies are sharing the same algorithm in calculating space vector duty-cycles. The one for DC-AC inversion together with the maximum constant boost control method can achieve the controllable boost-type DC-AC inversion after topologically coupling a Z-source network at the power stage. Both the two PWM strategies were verified by simulated implementation in a new converter based on matrix converter theory and Z-source inverter concepts for the study of ISA 42 V PowerNet
