Abstract

See full text

An illustrative device includes a first silicon-controlled rectifier (SCR) and a second silicon-controlled rectifier (SCR) connected in anti-parallel and a first commutation module, which includes a first voltage source, a first diode, and a first self-commutating semiconductor switch. The device also includes a second commutation module including a second voltage source, a second diode, and a second self-commutating semiconductor switch. The first voltage source, the first diode, and the first self-commutating semiconductor switch of the first commutation module are connected in series. The second voltage source, the second diode, and the second self-commutating semiconductor switch of the second commutation module are connected in series. The first SCR, the second SCR, the first commutation module, and the second commutation module are connected in parallel. The commutation modules are configured to apply reverse bias voltages to the first and second SCRs to turn off the SCRs.
