Asymmetric half-bridge with reduced switch load |
摘要 |
A circuit arrangement for two serially connected semiconductor switches connected to a voltage supply is provided. Between the semiconductor switches a primary winding of a transformer is connected. A first diode is connected on an anode side to a potential of the voltage supply at a source terminal of the second semiconductor switch and on a cathode side to a first connection terminal facing the first semiconductor switch on the primary winding. A second diode is connected on the cathode side to the potential of the voltage supply at a drain terminal of the first semiconductor switch and on the anode side to a second connection terminal facing the second semiconductor switch on the primary winding. A first secondary winding of the transformer is provided, connected in series between the first diode and the first connection terminal, and a second secondary winding, connected in series between the second diode and the second connection terminal. |
