Bridge for driving a direct-current or alternating current load |
摘要 |
A DC/DC bridge having a power stage provided with controllable semiconductor switches controls a direct currently load, and comprises two bridge sections, one of which bridge sections conducts direct currently while the other bridge section is controlled via pulse width modulation to regulate the current magnitude. Two of three bridge arms of the DC/DC bridge are connected in parallel and semiconductor switches in the parallel-connected bridge arms are controlled via pulse width modulation to form a pulse width modulation controlled bridge section.
