Abstract

See full text

The invention relates to a switch mode power supply (202) including a switch element (308) having an NPN-bipolar transistor (402) and a self-conductive field effect transistor (404). The NPN-bipolar transistor (402) and the field effect transistor (404) are connected to form a cascode (400). The NPN-bipolar transistor (402) is electrically connected to a winding (502) of a transformer (504), and an additional winding (508) of the transformer (504) is electrically connected to a base connection (408) of the bipolar transistor (402).
