Abstract: A control method for improving the efficiency of an inverter, relating to the technical field of inverters, and aiming to solve the problems of difficulty in design of Boost and INV inductors, large switching loss of switch transistors, and low efficiency. The present invention comprises the following implementation steps: S1, the voltage and current of Boost and INV lines are sampled; S2, when an absolute value of a mains voltage is greater than a threshold, the Boost circuit modulates an output voltage into a steamed bun waveform equal to the mains electricity; S3: when the absolute value of the mains voltage is less than the threshold, the Boost/Buck outputs a BUS voltage equal to the threshold, while the INV works at a high frequency, and modulates the BUS voltage into a zero-crossing portion of the mains voltage, and in this case, the Boost/Buck works in a constant voltage source mode or a pass-through mode, and the INV works at a high frequency but with low working voltage and small working current. Thus, it is ensured that the output work factor can be adjusted within a certain range, the loss of the Boost and INV lines can also be reduced, and compared with traditional control modes, the overall boost ratio of the Boost line and the utilization rate of the BUS voltage of the INV portion are reduced.
