Abstract
An alternating current generation circuit has a transformer and generates an alternating current voltage in accordance with a pulse signal input to the transformer. A clamp circuit has a constant-voltage element and a current limit element connected in series between the transformer, an output end of the alternating current voltage, and a ground. A direct current generation circuit generates a direct current voltage in accordance with a duty cycle of the input pulse signal. The direct current generation circuit converts, into a direct current voltage, a current that flows from the clamp circuit via the ground, and superimposes the direct current voltage on the alternating current voltage, and a voltage obtained by superimposing the direct current voltage on the alternating current voltage is output from the output end.
