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 Cinp and a second input filter capacitor Cinn, an output filter capacitor Co, 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 H2, a high-frequency isolation transformer M1, a high-frequency inductor Ls, 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 Cinp respectively. 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 Cinn respectively. A terminal of the primary-side hybrid five-level unit is coupled to a midpoint between the first input filter capacitor Cinp and the second input filter capacitor Cinn connected in series. The primary-side hybrid five-level unit is coupled to a primary side of the high-frequen…
