Magnetron high-voltage circuit driving signal.
To turn on and off cook relay RY2. In high operation, the signals holds "H" level during micro-
wave cooking and 'I" level while not cooking.
In other cooking modes (variable cooking) the
signal turns to "H" level and "L" level in repetition according to the power level.
