Title:
FOUR-QUADRANT CONVERTER CONTROL APPARATUS FOR FREQUENCY MULTIPLICATION SWITCHING, AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/082445
Kind Code:
A1
Abstract:
A four-quadrant converter control apparatus capable of realizing frequency multiplication switching, and a control method thereof. The four-quadrant converter control apparatus comprises a control strategy unit (20) and a carrier switching strategy unit (21) which separately perform control, wherein the carrier switching strategy unit (21) comprises a converter state information module (211), a frequency switching determination module (212), a heat dissipation calculation module (213), a switch frequency designation module (214), a carrier period calculation module (215), a carrier control module (216) and a carrier switching occasion determination module (217); the control strategy unit (20) comprises a control sampling processing module (201) and a modulation wave calculation module (202); the output of the control strategy unit (20) is a modulation wave signal and the output of the carrier switching strategy unit (21) is a carrier signal; the modulation wave signal and the carrier signal simultaneously enter a pulse width modulation (PWM) pulse modulation module (22) for modulation, such that a PWM pulse is outputted, thereby realizing control over a four-quadrant converter (10).
