A four-terminal snubber capacitor (10) according to the present invention is used in an inverter circuit (1), and is provided with: a snubber capacitor main body (100); a first bus bar (110) having a first terminal (111) to be connected to a terminal on the positive electrode side of a smoothing capacitor (101), and a second terminal (112) to be connected to the drain terminal of a MOSFET (102) on the positive electrode side; and a second bus bar (120) having a third terminal (121) to be connected to a terminal on the negative electrode side of the smoothing capacitor (101) and a fourth terminal (122) to be connected to the source terminal of a MOSFET (103) on the negative electrode side. The four-terminal snubber capacitor (10) according to the present invention makes it possible for surge voltages occurring during switch-off, and noise occurring during switch-off, to be reduced in comparison with conventional snubber capacitors. |
