Enhanced intelligent constant-current constant-voltage power supply

The utility model discloses an enhanced intelligent constant current and constant voltage power supply, comprising a commercial power input, a rectification filter, a full bridge inverter, an output filter and a core control unit, the core control unit is provided with a communication module, an I/O expansion module, a gear control module and a feedback sampling module, the commercial power inputcarries out EMI filtering on a 220V AC voltage, and the feedback sampling module carries out EMI filtering on the 220V AC voltage. After overvoltage protection and surge protection, the DC voltage issent to the rectification filter circuit, commercial power synchronous pulses are formed to the core control unit, the rectification filter provides the filtered DC voltage for the full-bridge inverter, the full-bridge inverter inverts the DC voltage into sine AC with set frequency and amplitude, and the sine AC with set frequency and amplitude is output to the core control unit. The core controlunit carries out real-time
