Abstract
A kind of power switch device having a switch circuit that forms switch output of intermittent pulse waves to the input power, an output circuit that transforms the aforesaid switch output into direct current, and a digital control part that controls the actions of the switch circuit; power switch device accepts the analog signals of output voltage from the output circuit, and transforms the analog signals of output voltage and analog signals of output current into digital signals, calculates at least the switch cycle of the switch circuit based on the digital signals of the aforesaid output voltage and output current, and calculates at least a command value that decides the on time or off time, turns the aforesaid command value into control pulse which is supplied to the aforesaid switch circuit and controls its opening/closing action, and the aforesaid digital control part has the function to decide the power input voltage based on the digital signals of output voltage and the digital signals of output current.
