Abstract :
A newly developed high-performance 3φ CVCF power conversion conditioner incorporating a novel quasi-resonant DC link (QRDCL) single-phase inverter with pulse width modulation (PWM) function and high-frequency AC transformer linked cycloconverter topology is presented. The operating characteristics of the proposed QRDCL inverter are discussed on the basis of computer-aided simulation results. In order to achieve a significant improvement in high performance and quick control response, a specially designed voltage pulse distributed vector control modulation scheme is introduced employing a digital signal processing software-based control implementation
