Title: Non-Rotation Type Alternating Current Generator Capable of Mulitplying Output Voltage
Inventor: CHOI WOO HEE
IPC: H02K99/00

Abstract: The present invention relates to a non-rotating alternating current generator capable of increasing output voltage. The non-rotating alternating current generator capable of increasing output voltage comprises: a direct current (DC) power supply part (110); a control part (120) providing a switching signal; and an alternating current output part (130). The alternating current output part (130) includes an iron core (131), pole pieces (133), a field winding (134, 135) receiving the direct current power, and an armature winding (136) wound on the iron core (131) between the pole pieces (133) to output the alternating current power by an induced electromotive force by the field winding (134, 135). The non-rotating alternating current generator further comprises a power supply (140) connected between the alternating current output part (130) and the direct current power supply part (110), and performing the role of supplying power to continuously output an alternating current from the alternating current output part (130) by supplying constant direct current power from the direct current power supply part (110) to the alternating current output part (130). An electromotive force can be obtained by rotation of magnetic flux by movement of electrons simply by turning on/off constant-duty power to the field winding stacked in a unit which is an alternating current output part. Direct current (DC) power is used to supply power by disconnecting power by a set duty. While providing a field with different directivities, an alternate electromotive force of a form similar to rotation of a conventional rotating synchronous generator is generated.
