ABSTRACT:
The disclosure is concerned with enabling modular power converter systems, including RF generators or transmitters involving such conversion, employing switching components such as SCRs in the power conversion, to fail in a soft manner as a result of transient electrical or other disturbances so as to permit continued system operation, through the use of individual module d.c. power supplies and circuit design that insures inverter module high output impedance even under SCR failure conditions and that mitigates against SCR failures caused by changes in load phase angle.
