A master-slave type IGBT drive circuit

A master-slave type IGBT drive circuit includes a master drive module, a master IGBT, at least one slave IGBT, a master acquisition and processing circuit, at least one slave acquisition and processing circuit, and at least one comparison and compensation circuit. At the present application, a voltage or current signal in the drive loop of the main IGBT is detected as a reference signal for all slave IGBTs, a corresponding voltage or current signal from the IGBT drive loop is detected as a feedback signal, after comparing the feedback signal with the reference signal, a regulating current is generated and injected directly into the gate loop of the slave IGBT to compensate feedback signals, the feedback signal can quickly track the reference signal, and the driving signals of all the slaveIGBTs can track the unique master IGBT driving signals, so that the driving signals of each IGBT are consistent, the driving asynchrony problem caused by different driving paths is eliminated, and the current balance of each
