Abstract
Power supply apparatus, especially for the active circuits of a portable radio communication device. The power supply supplies a direct voltage to a load that is connected to a first terminal, is comprising a rechargeable battery for connection to a second terminal, and a voltage generator for recharging the battery and supplying power to the load. The power supply includes first control means for controlledly supplying current from the voltage generator to the first terminal so as to control supply of current from the voltage generator to the load and for preventing reverse flow of current from the first terminal to the voltage generator, and second control means for controlledly supplying current between the first and second terminals so as to control supply of current from the voltage generator through the first control means to the battery and from the battery to the load.
