Title:
WIRELESS CHARGING VOLTAGE STABILIZING CIRCUIT, POWER SUPPLY, AND NEW ENERGY VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/213261
Kind Code:
A1
Abstract:
A wireless charging voltage stabilizing circuit, a power supply, and a new energy vehicle. The circuit comprises: a chip (1), used for comparing a battery voltage with a reference voltage and outputting a control signal, so as to control an MOS module (2) to switch between boost and buck topology modes. The chip (1) controls the duty ratio of a switching tube of the MOS module (2) on the basis of a periodic signal from a control unit (3). The problem of an unstable output voltage caused by change of a power supply voltage of a wireless charger along with the change of a battery is solved. In addition, by controlling the duty ratio of the switching tube of the MOS module (2) and adjusting the output voltage, the wireless charger can charge a mobile phone at any power within an allowable range.
