Abstract

The invention discloses a leakage protection circuit of a vehicle-mounted inverter and a corresponding vehicle-mounted inverter, and relates to the field of inverters. The leakage protection circuit comprises a shell, a circuit protection shell, a heat absorption box and a heat absorption aluminum plate, the vehicle-mounted inverter is installed in the shell through screws, and the circuit protection shell is arranged on the other side of the shell; a heat absorption box is installed at one end of the circuit protection shell through screws, an installation cavity is formed in the circuit protection shell, a heat absorption aluminum plate is installed on one side in the installation cavity through screws, and a protection circuit board is installed at the top of the heat absorption aluminum plate through screws. The top of the protection circuit board is provided with a leakage protector through screws, and one end of the leakage protector is welded with a processing chip. The novel vehicle-mounted inverter is provided with a protection circuit, effectively achieves the effects of voltage stabilization and current stabilization, is obvious in heat dissipation effect, has a leakage protection function, and is suitable for being widely popularized and used.

Description

technical field [0001] The invention relates to the technical field of inverters, in particular to a leakage protection circuit of a vehicle-mounted inverter and a corresponding vehicle-mounted inverter. Background technique [0002] Vehicle-mounted inverter is a kind of DC12V direct current that can be converted into AC220V alternating current that is the same as mains power. It is used for general electrical appliances. [0003] The previous vehicle-mounted inverters have the following disadvantages: 1. The vehicle-mounted inverter does not have a protection circuit, it is easy to overvoltage and overcurrent, the heat dissipation effect is not obvious, and it does not have the function of leakage protection. Therefore, those skilled in the art provide a leakage protection circuit for a vehicle-mounted inverter and a corresponding vehicle-mounted inverter, so as to solve the problems raised in the background art above. Contents of the invention [0004] The main purpose ...
