A design scheme of synchronous-meter simulation device based on three-phase SPWM inverter is presented, and the system architecture and circuit topology are proposed. The three-phase SPWM inverter is constructed by IPM intelligent model PS21563 and three-phase PWM chip SA8282. By microcontroller, two sine voltages with given frequency are gellerated to drive the synchronous-meter, the phase contrast is measured and output at the same time. The success application of the synchronous-meter simulation device in the ship power station simulator shows that the proposed simulation method has high control accuracy, can simulate different kinds of synchronous-meter actuarially, and possesses high versatility.
