ことを特徴とする充電回路。[Claims for Utility Model Registration] A plurality of sets of current detection units with different set values are provided, and the detection operation of the detection units generates a signal when the amount of current flowing through the primary coil 21 exceeds a set value. An inverter-type charging circuit that controls the output from the output coil 29 by controlling the off timing of the switching element 20 interposed in the current supply circuit to the primary coil 21 in conjunction with the current detection circuit. The charging circuit is characterized in that the detected voltage in the detection section on the high set value side has a large temperature characteristic on the negative side.
