摘要：
The design and implement action of a DSP-based fully digital-controlled single-phase pulsewidth modulated (PWM) dc-ac converter for ac voltage regulation is described. The proposed multiloop digital controller (MDC) consists of a current controller, a voltage controller, and a feedforward controller. This MDC was realized using a single-chip digital signal processor (DSP), The PWM gating signals are determined at Every sampling instant by the proposed multiloop digital control scheme using a set of detected feedback signals. A software current control scheme has been developed to achieve fast current control of the PWM inverter and decouple the inductor of the output filter Experimental results have been given to verify the proposed digital control scheme. The constructed DSP-based PWM dc-ac converter system can achieve fast dynamic response and with low total harmonic distortion (THD) for rectifier type of loads.
