This paper proposes a new pulse width modulation strategy for a voltage-source current-regulated soft switching inverter feeding an ac motor. By simply adjusting the three-phase current commands, the overall number of commutations per output cycle can be reduced. Based on this new strategy, the closed-loop speed control and position control of the ac drive system have been designed to achieve high performance dynamic responses. A 16-bit microprocessor system (80196MC) has been used to execute all of the control algorithms. Several experimental results validate the theoretical analysis. This paper presents a new direction in design and implementation of a high efficiency and high performance ac drive system.
