Power Supply Circuit With Zero Standby Power Consumption on Infrared Remote Controlled Product by Using Energy Harvesting

We propose a novel power supply circuit that can make a standby power consumption of an infrared remote (IR) controlled product completely zero. Our proposal is a hybrid power supply circuit combining the energy harvesting and conventional power supply structure. The IR controlled product employing our proposal has no pass of electric current in the standby mode. It is activated by the electromotive force that infrared photodiodes generate by receiving the infrared light from the remote controller. The activated product acts normally using the conventional power supply rail. These activation and control to the product are uniformly handled by a single remote controller. Although the conventional power circuit consumes the adequate standby power to be activated by the IR controller, our power circuit has actually achieved the zero standby power consumption of the IR controlled product and activated the electronic product by only electromotive force of photodiodes.
