Abstract (en)
A high-voltage transformer comprises an E-shaped core (100) and an I-shaped core. A high-voltage secondary winding (310) is located around the root of the central arm (111) of the E-shaped core (100). A low-voltage secondary winding (320) is also located around the central arm (111) and is separated from the high-voltage secondary winding (310) by magnetic shunts. The primary winding (300) is wound around the free end of the central arm (111) adjacent to the second secondary winding (320). This arrangement has been found to reduce radiated noise when used to drive the magnetron of a microwave oven. <IMAGE>
