Original Abstract Submitted

A drive circuit board includes a drive circuit that includes a first switching circuit including a first driver circuit configured to output a first drive signal and a first switching element configured to output a first switching signal, a second switching circuit including a second driver circuit configured to output a second drive signal and a second switching element configured to output a second switching signal corresponding to the first switching signal, a smoothing circuit configured to output the drive signal, and a stabilizing capacitor configured to stabilize a power supply voltage to be supplied to the first switching element and the second switching element, wherein a frequency of the first drive signal is higher than a frequency of the second drive signal, and a distance between the stabilizing capacitor and the first switching element is shorter than a distance between the stabilizing capacitor and the second switching element.
