Abstract:
(EN) An embodiment of the present invention relates to an alternating current (AC) power generator capable of adjusting frequency and voltage. The technical objective to be resolved is to provide a high-efficiency AC power generator capable of adjusting frequency and voltage, wherein AC power is generated by using direct current (DC) power such that the frequency and voltage of the AC power can be adjusted dynamically. To this end, the present invention provides an AC power generator comprising: a DC power supply portion; a control portion for providing a switching signal such that DC power having a frequency and a pulse width is supplied from the DC power supply portion; and an AC output portion configured such that, according to the switching signal from the control portion, the DC power is converted into AC power, which is then output, wherein the AC output portion comprises: an iron core; magnetic pole pieces arranged in the longitudinal direction of the iron core; a first field winding that is wound around the iron core in the forward direction between the magnetic pole pieces such that the DC power is supplied thereto; a second field winding that is wound around the iron core in the backward direction between the magnetic pole pieces such that the DC power is supplied thereto; and an armature winding wound around the iron core between the magnetic pole pieces so as to output the AC power by means of an electromotive force induced by the first and second field windings.
