Compact full-bridge DC-DC isolated power supply design circuit schematic

MOS power IC full range

One-piece inductor

Overview:
The new power electronics IGBT is the core component of the power converter, and its drive and protection circuits are critical to the reliable operation of the converter. The integrated drive is a self-contained independent drive board with the advantages of easy installation, high drive efficiency and reliable protection. It is the best way to drive and protect large and medium power IGBTs. The integrated driver generally includes four functional circuits such as on-board DC-DC isolated power supply, PWM signal isolation, power amplification, and fault protection. The functional circuits cooperate with each other to complete the driving and protection of the IGBT. The input power supply supplies power to each functional circuit on the primary side of the board. The two DC-DC isolated power supply outputs drive the upper and lower half-bridge switching tubes respectively, and provide power for the IGBT side fault detection and protection circuit. Therefore, the power supply on the integrated driver board is all. The premise and basis of the circuit work.
