It functions in such a way that it can effectively be thought of as an electronic transformer with a pulsed DC output voltage. It combines the advantages of conventional variable transformers, such as amplitude control and sinusoidal supply loading, with the advantages of thyristor power switches, such as current limiting, load monitoring, underlying control loops and so on. There is no electrical isolation between the supply voltage and the load voltage. The converter is suitable for all those applications where substantial resistive loads have to be switched. Thanks to the amplitude control (i.e. the current drawn from the supply is always sinusoidal), synchronous clock controls (as for burst-firing operation) or powerfactor compensation networks (to compensate for phase-control reactive power) are not required.
