Abstract: An electrical power conversion device, a function triggering circuit for the electrical power conversion device, and a function triggering method for the electrical power conversion device are provided. The function triggering circuit is coupled between the secondary side of the transformer and the control module and includes a current detection circuit, a delay circuit and a switching circuit. The current detection circuit senses the secondary side of the transformer to generate a detection signal of delay. Before steady-state duty of the transformer, the delay circuit causes an initial level to be higher than an internal level. After steady-state duty of the transformer, the switching circuit selectively generates a function triggering signal according to the detection signal. The function triggering signal is for triggering the control module to carry out an overcurrent protection operation. Therefore, the electrical power conversion device effectuates electrical power conversion precisely and steadily, provides precise overcurrent protection, and achieves low stand-by power consumption.

Abstract: A power supply system with current sharing includes a current sharing bus, a plurality of power supply units, and a plurality of controllers. The power supply units are connected to each other through the current sharing bus. Each power supply unit provides a current sharing signal value to the current sharing bus, and provides an output current to a load. Each controller receives current sharing signal values provided from other power supply units and current signal values corresponding to the output currents. When determining that the current signal value is less than a reference current sharing signal value, the controller increases an output voltage of the power supply unit to increase the output current. Otherwise, the controller decreases the output voltage to decrease the output current so that so that the output currents of the power supply units are shared to supply power to the load.
