Abstract :
A high-performance current-regulated single-phase DC/AC converter module is proposed. Its features include a two-switch topology with no short-through paths, high output to input voltage gain, low and constant switching frequencies, and practically instantaneous recovery from input or output transients. By utilizing an inner filter capacitor current control loop, the module can maintain nearly perfect sinusoidal output voltages, even with highly nonlinear loads. Three-phase operation can be obtained by using three of these modules. The analysis and design of the converter power and control circuits and the experimental confirmation of key predicted results are presented.<>
