Main circuit of 2000W vehicle-mounted inverter

The invention discloses a main circuit of a 2000W vehicle-mounted inverter, which relates to a main circuit of a vehicle-mounted inverter. The problems that an existing vehicle-mounted inverter is small in power and limited in use are solved. Positive and negative signal input ends of two 1000W topological circuits are respectively connected with positive and negative electrodes of a battery, positive electrode output ends of the two 1000W topological circuits are connected with one end of a rectifying and filtering capacitor, and negative electrode output ends of the two 1000W topological circuits are connected with the other end of the rectifying and filtering capacitor; one end of the rectifying and filtering capacitor is also connected with a high-voltage side signal input end of the inverter circuit, and the other end of the rectifying and filtering capacitor is also connected with a low-voltage side signal input end of the inverter circuit; a signal output end of the inverter circuit is connected with a
