Claim 7:
8. The drive circuit according to claim 3, wherein
the chopper circuit includes:
an inductor, wherein a first end of the inductor is connected to one of the positive-side terminal or the negative-side terminal;
a first transistor, wherein
a source of the first transistor is connected to a second end of the inductor,
a drain of the first transistor is connected to the node, and
a first pulse width modulation signal is input to the first transistor; and

a second transistor, wherein
a source of the second transistor is connected to the second end of the inductor,
a drain of the second transistor is connected to a ground terminal,
a second pulse width modulation signal is input to the second transistor, and
a phase of the second pulse width modulation signal is opposite to a phase of the first pulse width modulation signal.
