In a reversible buck-boost chopper circuit, a first half-bridge circuit has a first switching element with a high-side main electrode connected to a positive electrode of a DC power source, and a second switching element is connected to the first switching element at a first output terminal. A low-side main electrode of the second switching element is connected to a negative electrode of the DC power source. A second half-bridge circuit has a third switching element with a high-side main electrode connected to a high-side terminal of the load. A fourth switching element of the second half-bridge circuit is connected to the third switching element at a second output terminal. A low-side main electrode of the fourth switching element is connected to a low-side terminal of the load and the negative electrode. A reactor is connected between the first and second output terminals. |
