Title:
VOLTAGE STABILIZING CIRCUIT FOR ON-BOARD BATTERY POWER SUPPLY, AND CHARGING SOCKET FOR NEW ENERGY VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/051576
Kind Code:
A1
Abstract:
A voltage stabilizing circuit for an on-board battery power supply, and a charging socket (71) for a new energy vehicle. The voltage stabilizing circuit comprises: a voltage stabilizing module (61), which has several pins; and a peripheral module. The peripheral module comprises: a filter circuit (621), which is connected to an input pin (8) of the voltage stabilizing module (61), and is used for receiving an on-board battery power supply and for filtering out noise fluctuations of the on-board battery power supply, so as to obtain a direct-current voltage; a pulse switch circuit (622), which is used for receiving a turning-on signal from a driving pin (6) of the voltage stabilizing module (61), so as to generate a pulse voltage; a coupling and rectification circuit (623), which is connected to the pulse switch circuit (622), and is used for coupling the pulse voltage with the direct-current voltage and then performing rectification thereon, so as to obtain a guiding voltage; and a voltage division circuit (624), which is used for dividing the guiding voltage and then feeding same back to a feedback pin (3) of the voltage stabilizing module (61). The voltage stabilizing module (61) controls the duty cycle of the pulse voltage according to a voltage division result until the guiding voltage meets guiding requirements, and adjusts, according to a feedback signal, the driving pin (6) to turn on/off a field-effect transistor (51) so as to adjust the duty cycle of the pulse voltage, such that after the pulse voltage and the on-board battery power supply are coupled and rectified, a stable guiding voltage is obtained.
