Multi-channel isolation direct-current power generator

The utility model relates to the field of power supplies, in particular to a multi-channel isolation direct-current power generator. The utility model meets the current requirement of electronic laboratories, prior electronic devices and systems on multiple channels of power supplies. The power generator comprises an AC/DC power module or a transformer, a rectifier bridge, a plurality of channels of power output regulator circuits, optocoupling relays and a time gating control circuit consisting of a programmable logic device CPLD and a crystal oscillator, the anode of the light-emitting element of each optocoupling relay is connected with the output end of the CPLD through a protective resistor, photosensors are respectively connected in series between the output end of the rectifier bridge and the input end of each power output regulator circuit, and the input end of each channel of power output regulator circuit is connected in parallel with an electrolytic capacitor for storing energy. The utility model has the advantages of reasonable and simple structure and low cost, and can convert a single channel of alternating current into multiple channels of linear power supplies which are isolated from one another and stably outputted at voltages with different amplitudes or the same amplitude, and the utility model is applicable to electronic laboratories and various electronic device control systems.
