ABSTRACT:
A power source circuit has an electric energy generator, two condensers, a switching element and a voltage detecting circuit. The first condenser accumulates electric energy which is generated by the electric energy generator, such as a solar cell, and the second condenser supplies electric energy to a load. The switching element controls the electric energy transfer from the first condenser to the second condenser in response to the output of the voltage detecting circuit which detects the terminal voltage of the second condenser. The first condenser has a relatively high withstand voltage and relatively small capacity and volume so as to obtain a quick start-up operation of the circuit and a prolonged operation.
