Abstract
This paper presents a newly-developed high-performance 3¿CVCF power conversion conditioner incorporating a new Quasi-Resonant DC Link (QRDCL) single-phase inverter with PWM function and high-frequency AC transformer linked cycloconverter topology. The operating characteristics of a proposed QRDCLI are discussed on the basis of computer-aided simulating results. In order to achieve a significant improvement in high performance and quick control response, the specially-designed voltage Pulse Distributed vector control Modulation (Modified PDM) scheme is introduced through employing DSP software-based control implementation. In addition, this instantaneous voltage vector controlled 3¿CVCF power conditioning and processing system suitable for a low EMI, high-power density UPS is evaluated and discussed for linear and non-linear electrical loads under the conditions of large load variations from a practical point of view.
