Abstract
This paper considers the thyristor chopper circuits constituted of a power circuit (source, main thyristor, load and freewheeling diode), a basic commutation circuit and a voltage reversion circuit (to make the commutation capacitor voltage polarity adequate to commutate the main thyristor current). Different possibilities of connection of basic commutation circuits into the chopper power circuit and possible techniques for reversal of commutation capacitor voltage polarity are presented. As a result, derivation of large number of topologies is systematised.
