Inverter bridge section arrangement, has semiconductor switch supplied with series circuit from unipolar voltage source, and connection node connected with bridge point of inverter bridge section between coils
The arrangement has a connection node connected with a bridge point of an inverter bridge section between two coils (L1, L2). A semiconductor switch (T2) e.g. MOSFET and insulated gate bipolar transistor, comprises a series circuit and other two coils (L3, L4) and is switched in series. The latter coils are magnetically coupled, form a transformer, and are formed as windings on a common core. The switch is supplied with another series circuit from a unipolar voltage source. The connection node is connected with the bridge point of the inverter bridge section between the latter coils. An independent claim is also included for a method for operating an inverter bridge section arrangement.
