ABSTRACT:
There is provided a charging system for secondary batteries comprising a high-frequency power supply circuit consisting of a transistor DC-DC converter and a control circuit for preventing the overcharging of a battery to be charged, whereby the oscillation of the high-frequency power supply circuit is controlled by the control circuit. Thus, the size and weight of the charging system of this invention are reduced.
