Circuit arrangement for driving power transistors

摘要

To prevent relatively high drive losses of a power transistor (3) arranged in a direct-current chopper, which has a choke coil (4) in the collector circuit, a switching transistor (2), the collector of which is connected to a tap of the choke coil (4) and the emitter of which is connected to the base of the power transistor (3) is provided for driving purposes. <IMAGE>
