Abstract:
1. A configurable power supply system, comprising: a power source, for providing input power; a switch, coupled to the power source, for enabling a bypass path for outputting the input power to an output node as an output power when turned on; a rechargeable battery module, for storing the input power and outputting a battery power; a charging unit, coupled between the power source and the rechargeable battery module, for charging the rechargeable battery module with the input power; a converting unit, coupled to the rechargeable battery module, for converting the battery power to generate the output power; and a control unit, coupled to the switch, the charging unit, and the converting unit, for controlling functions of the switch, the charging unit, and the converting unit; wherein the control unit controls a current provided for the charging unit for charging the rechargeable battery module, to control the functions of the charging unit, the control unit further determining a relationship between a voltage of the output power and a voltage of the input power; wherein when the voltage of the output power is far from the voltage of the input power, the control unit controls the switch to be turned off and the converting unit to be turned on, for outputting the output power by converting the battery power to generate the output power; and when the voltage of the output power is close to the voltage of the input power, the control unit controls the switch to be turned on and the converting unit to be turned off, for outputting the output power by passing the input power through the bypass path to generate the output power, or controls the switch to be turned off and the converting unit to be turned on, for outputting the output power by converting the battery power to generate the output power.
