Original Abstract Submitted

A drive circuit board includes a first driver circuit configured to output a first drive signal, a first switching element pair configured to output a first switching signal, a second driver circuit configured to output a second drive signal, a second switching element pair configured to output a second switching signal, and a smoothing circuit configured to output the drive signal, wherein a distance between a source terminal of a first high-potential side FET provided to the second switching element pair and the smoothing circuit is shorter than a distance between a drain terminal of the first high-potential side FET and the smoothing circuit, and a distance between a drain terminal of a first low-potential side FET provided to the second switching element pair and the smoothing circuit is shorter than a s distance between a source terminal of the first low-potential side FET and the smoothing circuit.
