| Abstract: | The conventional fault signal of IGBT driver circuit is transmitted by low speed photocoupler,such as TLP521 or PS2501.It may cause problems in some working conditions.One of the solutions is to replace the photocoupler by optical fiber.The experiment based on 1200V/200A IGBT driver circuit has proved its superior performance in far distance transmission of PWM signals. |
