Abstract:
A power supply circuit comprising: a load; a resistor coupled the load; a first secondary battery; a second secondary battery; a switch configured to switch between a first state in which the first secondary battery and the second secondary battery are charged and a second state in which load current is supplied from the first secondary battery and the second secondary battery to the load based on current flowing through the resistor; and a shunt regulator configured to control the switch.
