Abstract

The invention discloses a charging module fault communication system and method, and belongs to the technical field of communication. A PFC circuit, a DC-DC circuit, a first control chip and a second control chip are arranged in a charging module fault communication system, and the PFC circuit is used for controlling a current waveform input by a charging module, so that the current waveform is synchronized with a voltage waveform input by the charging module; the DC-DC circuit is used for converting the voltage input by the charging module; the first control chip and the second control chip are used for acquiring PWM frequency information and performing corresponding circuit control when a certain level of circuit of the charging module fails or input and output emergencies occur, so that information intercommunication between power conversion links can be quickly realized, quick protection response is performed on the circuit of the charging module, and the service life of the charging module is prolonged. And the fault processing capability of the charging module is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a charging module failure communication system and method. Background technique [0002] The charging module contains two power conversion links. The first link is the front-stage AC-DC link, which is generally realized by PFC; the second link is the rear-stage DC-DC link, which is generally realized by LLC circuit or full-bridge shifting equalization technology. , between the two power conversion links, it is necessary to transmit signals such as control quantity and protection quantity. When a circuit of a certain stage of the charging module fails or an emergency occurs in the input and output, a fast communication method is needed to realize the two power conversion links. The information exchange among them is to realize the fast protection response of the power conversion link. [0003] The existing communication method is realized by I / O port communication method t...
