Abstract
A GaN-FET (10) having a small resistance at the time of conduction is disposed in the path of a main current that flows between an input terminal (11) and an output terminal (12) . Moreover, there are provided a Zener diode (ZD) and a resistor (R) for setting an output voltage (Vout). As a result, reduction of size and weight is realized, and design including radiation design can be conducted flexibly. Time and labor required for design are remarkably reduced.
Claims10
A power supply apparatus comprising:
- a semiconductor element, disposed in the path of a main current that is a subject of power control, and formed by using a GaN compound;
- and
- a control unit which controls conduction of the main current flowing through said semiconductor element.
A power supply apparatus comprising:
- a semiconductor element, disposed in the path of a main current that is a subject of power control, and formed by using a GaN compound;
- and
- a control unit which conducts switching control on conduction of the main current flowing through said semiconductor element.
A power supply circuit having a transformer, and which conducts on/off control on voltage applied to a primary winding of said transformer, and thereby supplies a stabilized power supply voltage to a secondary winding side of said transformer, further comprising:
- a GaN-FET connected to the primary winding of said transformer and on/off-controlled by a gate signal.
A large current load current load control apparatus that conducts on/off control on a current supplied from a power source according to a predetermined instruction and supplies a resultant current to an electric load, said large current load current load control apparatus comprising:
- a GaN-FET, connected to a power source line that connects said source to said load, and which conducts the on/off control.
