Abstract
The present disclosure discloses a hybrid five-level bidirectional DC/DC converter and a voltage match modulation method thereof. The converter includes a first input filter capacitor Cand a second input filter capacitor C, an output filter capacitor C, a DC voltage source, a primary-side hybrid five-level unit, a primary-side two-level half bridge, a secondary-side single-phase full bridge H, a high-frequency isolation transformer M, a high-frequency inductor L, and a controller. A positive pole of a DC bus of the primary-side hybrid five-level unit is coupled to a positive pole of the corresponding DC voltage source and to a positive pole of the input filter capacitor Crespectively. A negative pole of the DC bus of the primary-side hybrid five-level unit is coupled to a negative pole of the corresponding DC voltage source and to a negative pole of the input filter capacitor Crespectively. A terminal of the primary-side hybrid five-level unit is coupled to a midpoint between the first input filter capacitor Cand the second input filter capacitor Cconnected in series. The primary-side hybrid five-level unit is coupled to a primary side of the high-frequency isolation transformer Mthrough the high-frequency inductor L, and a midpoint of the primary-side two-level half bridge is coupled to another terminal of the primary side of the high-frequency transformer.
