Dual-output two-stage matrix converter modulation method based on carrier PWM

The invention relates to a dual-output two-stage matrix converter modulation method based on carrier PWM. The dual-output two-stage matrix converter modulation method based on carrier PWM is characterized in that: for a rectification stage, an input phase voltage is divided into six sectors, and two line voltages with the largest amplitude and positive polarity are selected in each sector to synthesize an output direct current voltage, and a corresponding duty ratio is calculated; for an inverting stage 1 and an inverting stage 2, space voltage vector modulation is adopted to calculate the duty ratios of an effective voltage vector and a zero voltage vector according to the sector in which a reference voltage vector is located; reasonable optimization of the switching state of the rectification stage and the inverting stage is carried out; and a PWM signal diagram of the power switch is drawn according to the whole modulation process, and the modulation signals of the six bidirectionalpower switches of the re
