Induction Heater C Library User Manual Version 1.2 5. Module Description 5.1. Power Module The 220V is connected by “ICN1 ” and “ICN2 ”. The 220V is rectified by “U4 ”, and supplied to the pad. The “U11 ” is a 15V power module. It supply power to the MCU and IGBT driver. 5.2. IGBT Driver Module The “START ” is the system enable signal. When it is high, the system is enabled, else disabled. The “PPG-IGBT ” is the IGBT drive signal. When it is high, the IGBT is opened, else closed.

Induction Heater C Library User Manual Version 1.2 5.3. Pad Driver Module When the IGBT (U9) is opened, the current flow over the “PAD ”. The “PAD ” is a coil, so it will save the power. The current direction is from left to right. Once the IGBT is closed, because the “PAD ” is a coil, the current direction is still from left to right. Because there is a C11, so it and the “PAD ” are made an oscillation loop, and the power will be saved in the C11. When the system is working, if there i
