| Abstract |
Magnetic flux saturation depend on phase of initial input power to high voltage transformer used in Micro wave oven. To limit inrush current high voltage transformer the relay contact should be "ON" when the lowest point of input voltage phase. The improved circuit is for compensating interrupt signal Micom input so the relay contact can be "ON" when the inrush current is lower. Test results are presented that improved circuit satisfies the limit 50[A] of requirement for input voltage variation mode. And the result verified by statistical method. |
