摘要: This paper presents a new modulation method for the cycloconverter stage of high frequency (HF) link AC-DC rectifier. The takes advantage parasitic parameters circuit to provide zero current switching (ZCS) AC-and voltage (ZVS) DC-side transistors. Regulation with power factor correction (PFC) is ensured using only one control variable and no external auxiliary or snubber circuits are required. Moreover, 1/4 AC-side transistors operating fundamental frequency. proposed strategy its design constraints analysed mathematically verified simulation model 1 kW, 230 VAC/48 VDC HF-link converter.
