| description | The utility model discloses a three-level switching power supply system, which comprises a BOOST converter, a resonant converter and a rectifying circuit which are connected in sequence, wherein the first switch tube is connected with the second switch tube in series, the source electrode of the second switch tube is connected with the cathode of the second diode, the anode of the second diode isconnected with the resonant converter, the second diode is arranged on the cathode bus, and one end of the first capacitor is connected with the cathode of the first diode. Only one inductor is needed; the three-level BOOST transformer is driven in a staggered manner; ripples of inductive current are greatly reduced, inductive loss can be effectively reduced, ripple voltage and ripple current on abus capacitor are effectively suppressed, and a BOOST converter, a resonant converter and a rectifying circuit are combined to form the efficient, low-cost and high-reliability switching power supplyof which the withstand vol |
