Abstract
There is provided a phase shift full bridge (PSFB) type power supply device controlling a switching on time of lagging leg switches according to a load state. The power supply device includes a power supply unit supplying preset DC power by switching input power using a full bridge by a phase shift method; and a control unit controlling a switching time of a switch of the full bridge according to a load state in which the DC power is received from the power supply unit.
Claims14
A power supply device, comprising:
- a power supply unit supplying preset DC power by switching input power using a full bridge by a phase shift method;
- and
- a control unit controlling a switching time of a switch of the full bridge according to a load state in which the DC power is received from the power supply unit.
A power supply device, comprising:
- a power supply unit supplying preset DC power by switching input power using a full bridge by a phase shift method and rectifying and stabilizing transformed switching power;
- and
- a control unit controlling a switching time of a switch of the full bridge by determining a load state in which the DC power is received from the power supply unit, based on resonance between the switch of the full bridge and an output capacitor and a parasitic inductor of a rectifying switch.
