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 device having variable output voltage includes a controller, and a first power supply module and a second power supply module connected in parallel. The controller selectively outputs a first voltage control signal and a first switch control signal to the first power supply module, or outputs a second voltage control signal and a second switch control signal to the second power supply module according to a voltage requirement signal. An output power of the first power supply module has a first voltage value selected from a first voltage value set, an output power of the second power supply module has a second voltage value selected from a second voltage value set, and a minimum value of the first voltage value set is greater than a maximum value of the second voltage value set. Thus, more extensive voltage output capabilities are provided, and good power conversion efficiency is achieved at the same time.

Abstract: An inverting apparatus and an AC power system are provided. The inverting apparatus includes an inverting circuit, a detection circuit, and a control circuit. The inverting circuit receives a DC input voltage and converts the DC input voltage into an AC output voltage. The detection circuit samples the AC output voltage and compares the sampled AC output voltage respectively with a first reference voltage and a second reference voltage so as to generate a first indication signal and a second indication signal. The control circuit controls the operation of the inverting circuit. The control circuit determines whether the amplitude of the AC output voltage is located within an operating voltage range during each driving cycles according to the first and the second indication signals, and decides whether to enable an overvoltage protection or an undervoltage protection to control the power conversion of the inverting circuit according to the determination results.
