单电源九电平高频逆变器

Single power supply nine electric level high frequency inverter

Abstract

The invention discloses a single power supply nine electric level high frequency inverter, comprising a switch capacitor unit X, a reverse direction series connection switch tube unit Y and a full bridge unit Z. The switch capacitor unit X comprises a first electrolytic capacitor C1, a second electrolytic capacitor C2, a first diode VD1, a second diode VD2, a third diode VD3, a tenth diode VD10, an eleventh diode VD11, a first switching tube S1, a second switching tube S2 and a third switching tube S3; and the reverse direction series connection switch tube unit Y comprises a fourth diode VD4, a fifth diode VD5, a fourth switch tube S4 and a fifth switch tube S5. The full bridge unit Z comprises a sixth diode VD6, a seventh diode VD7, an eighth diode VD8, a ninth diode VD9, a sixth switching tube S6, a seventh switching tube S7, an eighth switching tube S8 and a ninth switching tube S9. The single power supply nine electric level high frequency inverter realizes nine electric levels through a single power supply and few devices.
