Dear everybody, We are now designing a transformer for microwave oven. Here is the basic spec,
input voltage: 120V rms output voltage: 2300V rms Thermal class: 200C We are facing the problem that we need to be compliace with UL1446 and UL 1585. They specify that all ground insulation need to be at least 5 mil Nomex for a 600V system. Then for 2300V system, by scaling the thickness of Nomex, do we need to increase the thickness to 18-20mil Nomex. Well, we can use Nomex at that thick but the cost of the whole unit becomes very high, any comments?
