With the rise of the charging level of new energy vehicles, the three-level half-bridge LLC topology is gradually applied to the rear stage of DC charging pile. This topology often adopts a hybrid control mode of Pulse Frequency Modulation (PFM) and Phase Shift Modulation (PSM) to obtain a wide outp...
