Abstract
Disclosed is a system and method for large-current power supply and constant-current control. Large-current power supply includes: primary power supply, energy-feedback circuit and direct-current (DC) large-current generator; energy-feedback circuit includes freewheel diode and magnetic reset winding; and secondary coil of DC large-current generator is connected to load. Without output rectifier diode and filter capacitor at load end of large-current power supply provided herein, power consumption problem of output rectifier diode at large current is unnecessarily considered, and electrolytic capacitor is not needed for filtration; and therefore, service life of power supply is greatly prolonged, larger current is output by extending, and power supply has advantages of simple circuit, small size, easy control and high working reliability. By adopting control method and system provided herein, an output voltage of Buck circuit in primary power supply is accurately controlled, and thus large-current power supply obtains a constant output current at load end.
