Abstract

The invention provides an anti-oscillation voltage regulating circuit and a wireless charging system. The anti-oscillation voltage regulating circuit comprises a processing chip, wherein the processing chip is used for sampling input current and input voltage of a rectifying circuit and outputting a corresponding PWM signal so as to adjust the duty ratio of output voltage; or the processing chip is used for acquiring sampling current between a second end of a first capacitor and a second output end of the rectifying circuit and outputting the corresponding PWM signal so as to adjust the duty ratio of the output voltage when a switch tube corresponding to a first control end and a second control end of the processing chip is switched off; or the processing chip is used for sampling the input current of the rectifying circuit and outputting the corresponding PWM signal so as to adjust the duty ratio of the output voltage when the switch tube corresponding to the first control end and thesecond control end of the processing chip is switched off. According to the anti-oscillation voltage regulating circuit, the generation of the current oscillation phenomenon in the voltage regulationprocess is avoided by the above mode.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an anti-oscillation voltage regulation circuit and a wireless charging system. Background technique [0002] At present, the wireless charging method of electric vehicles is widely used by automobile manufacturers because it is safer and more efficient. The specific working method of wireless charging is that the secondary coil is installed on the electric vehicle, and the primary coil is installed on the ground charging equipment. The electromagnetic field coupling of the primary and secondary sides is used to realize the non-contact transmission of electric energy between the primary and secondary sides. The purpose of wireless charging for electric vehicles. [0003] Since the position between the electric vehicle and the ground charging equipment is in an uncertain state with the parking state, and the position of the electric vehicle from the ground will a...
