Abstract :
A description is presented of a regenerative converter which allows the SCR power structure to operate as a synchronous line commutator, while a 2 transistor series/shunt chopper, with a power resistor, controls the regenerative power flow, and offers an emergency braking capability. In addition, SCR commutation is accomplished by the line voltage and diversion of bus current. Both simulation and experimental results are given.<>
