I am designing a one stage HVDC circuit breaker using LTSPICE software. Basically it consists of a circuit breaker (solid state like thyristor, IGBT etc) and a current commutation circuit in parallel which consist of a capacitor, inductor and energy absorbing circuit (a varistor or high resitor). I have a design based on theoretical model which I am trying to simulate in LTSPICE but it does not work. I am not sure how to control switching. I can attach the .asc file if required.
Thanks in advance.
