HF DC AC converter generating square wave signal - has two diodes connected anti-parallel to two DC sources

摘要

The h.f. d.c. to a.c. converter generates an output signal of square wave form. It has two d.c. supplies connected in series. It has at least three thyristor branches connected in parallel and coupled to the d.c. sources. Each thyristor branch has two main thyristors connected in series with two choke coils and a capacitor terminating at a middle connecting point of the thyristor arm. The other terminal of each capacitor is connected to the load. The other terminal of the load is connected to the coupling point between the d.c. supplies. Two diodes are joined anti-parallel to the two supplies. The connecting point between the diodes is joined to the connecting point between the load and the capacitors.
