Claims

[Scope of utility model registration request]

an energy bank that stores and releases electricity;
A primary power supply that supplies power to the energy bank, a power conversion circuit that receives pulsed current from the energy bank and converts power at high frequency, and a rectifier that rectifies and smoothes the output of the power conversion circuit.
a smoothing circuit, a control circuit that detects the output of the rectifier/smoothing circuit, generates a signal for controlling the voltage supplied to the load, and outputs it to the power conversion circuit; and an auxiliary power source that supplies power to operate the control circuit. circuit and
a relay having one of its contacts connected to the primary power supply, a saturable reactor connected to the other of the contacts of the relay, an inrush current prevention circuit installed between the saturable reactant and the energy bank, and the above-mentioned A DC power supply device comprising a diode that causes current to flow through the coil of the relay when the input voltage of the energy bank becomes higher than the output voltage of the primary power source.
