摘要： A novel switching power unit adopting a digital control system. The switching power unit is provided with a switch circuit (40) which switches input power, an output circuit (50) which outputs a switching output after converting the output into a direct current, and a digital control section (70). The section (70) receives an analog output voltage signal (AS1) and an analog output current signal (AS2) and converts the signals (AS1 and AS2) into digital signals. The section (70) also calculates a command value which decides at least one of the switching frequencies, turning-on time, and turning-off time of a main switch (42) based on the two digital signals and controls the switching operations of the switch (42) based on the calculated command value. Moreover, the section (70) estimates input power supply voltage information or load terminal voltage information from the digitized signals of signals (AS1 and AS2).
