Control method of DCM single-bridge-arm integrated split source boost inverter

The invention relates to a control method of a DCM single-bridge-arm integrated split-source boost inverter, which is applied to an independent inversion occasion in an output voltage stabilization mode, and comprises the following steps: acquiring a direct-current bus voltage, comparing the direct-current bus voltage with a direct-current bus voltage reference, and realizing direct-current side boost control through a direct-current bus voltage PI controller; obtaining an output voltage, comparing the output voltage with an output alternating current reference, and realizing sine and amplitude control of an output waveform through an output voltage PI controller. By means of the method, the DCM single-bridge-arm integrated split-source boost inverter can be applied to independent inversion occasions in an output voltage stabilization mode, the phenomenon of output waveform overmodulation during light-load operation can be effectively prevented, and the quality of output waveforms is improved.
