Abstract
The invention discloses a charging and inversion all-in-one machine comprising a current input unit, a switching unit, a bidirectional converter and a battery energy storage unit. The switching unit and the bidirectional converter are connected with a system control unit. The system control unit is connected with an LCD displayer. The bidirectional converter comprises four MOSFETs. When the converter works in an inversion mode, the four MOSFETs form a full-bridge inverter. Energy of a battery bus is reverted to sine wave to be outputted at the high-voltage side of a transformer through the SPWM modulated full-bridge inverter. When the converter works in a charging mode, left and right half-bridge MOSFETs are closed, and a dual BOOTS circuit is formed by the internal diodes and the low-end MOSFETs so that positive/negative half wave voltage boosting charging control is performed on energy which is transmitted by the transformer and lower than battery voltage via the dual BOOTS circuit and an APFC function in charging is realized by tracking of power grid input waveform.
