ABSTRACT
This chapter presents a design layout for a high-frequency, high-voltage transformer for use in a high-voltage switched mode power supply. The electrical specifications were determined by the output requirements of the power supply as well as the operating constraints of the power electronics that drives the transformer, for example, 20 kHz switching frequency. Conversion of AC mains voltages to a high-voltage, high-power depolarization current (DC) level is a key area of technology which is a requirement in many industrial processes, for example, in particulate emission control using electrostatic precipitators. In the majority of cases, the high-voltage DC requirement is achieved with a single-phase AC regulator, coupled to a large oil filled 50/60 Hz transformer. The design of a high-frequency, high-voltage, high-power transformer differs widely from the standard transformer design methodologies. The transformer design required consideration of the insulation materials, the magnetic material, and the management of electrical, magnetic, and thermal stresses.
