Abstract

The invention relates to a power supply control circuit applied to an electromobile charging guide circuit. The power supply control circuit comprises a pulse width modulation (PWM) signal generation module, a power supply control circuit output end and a switch, wherein the switch is arranged between the PWM signal generation module and the power supply control circuit output end, and an anti-interference circuit and a dead load circuit are arranged at the power supply control circuit output end. The invention also proposes the electromobile charging guide circuit and a charging pile. A dead load is additionally arranged at the power supply control circuit output end, and thus, the anti-interference performance is improved; and a magnetic bead is additionally arranged, a discharge interference voltage of a diode is suppressed in a bidirectional transient way, and the electrical fast transient (EFT) capability and the electro-static discharge (ESD) capability of the power supply control circuit are improved.

Description

technical field [0001] The invention belongs to the field of electric vehicle charging, in particular to a power supply control circuit, an electric vehicle charging guide circuit and a charging pile. Background technique [0002] With the rapid development of electric vehicles, as an important part of the electric vehicle development industry chain, electric vehicle charging equipment also emerges and develops continuously. Electric vehicle charging equipment is a supporting facility for charging electric vehicles, including charging stations, charging piles, battery scheduling, billing monitoring and battery equipment maintenance systems, and is the infrastructure to promote the development of electric vehicles. [0003] According to the type of power supply, charging piles can be divided into DC charging piles and AC charging piles. The DC charging pile mainly processes the AC power through transformation, rectification, inversion, filtering, etc. through power electroni...
