Abstract

PURPOSE:To save power by cutting off the power supply of a pulse width modulation signal amplifying circuit when the output voltage of a constant voltage circuit is used for another device. CONSTITUTION:The output voltage of the constant voltage circuit 9 is supplied to the pulse width moldulation signal amplifying circuit consisting of the pulse width modulation circuit 2 and a pulse power amplifying circuit 3 and the use of the output of the circuit 9 is ensured for another device 11. When the output voltage of the circuit 9 is used for another device, only a battery 11 for example, the power supply of the circuit 3 is cut off by turning off a connecting switch 12. Namely, a power supply switch 8 is turned on, a connecting switch 16 is turned on and the connecting switch 12 is turned off for charging only the battery 11.
