Abstract

A drive circuit for driving a square transformer, comprising a PWM modulation processing part, a DC protection part connected to the front end of the PWM modulation processing part, and a spark wire starting part. This makes it possible to drive square transformers with higher power and fewer primary turns.

Description

technical field [0001] The invention relates to the technical field of vehicle power amplifiers, in particular to a driving circuit for driving a square transformer. Background technique [0002] In order to enhance the sound effect of car audio, a car power amplifier for car use has been developed. The applicant has developed a high-power copper plate square transformer with small size, low electromagnetic interference, high power, low heat generation, high conversion efficiency, low heat generation, small DC impedance, good economic benefits, and easy installation. The primary winding The number of turns is small, such as one circle, so the driving circuit is required to have sufficient power and current. The driving current of the existing transformer driving circuit is small, the driving power is small, and the square transformer cannot be successfully driven. Contents of the invention [0003] In view of this, the present invention provides a driving circuit for driv...
