1. A converter circuit for converting a first ac voltage into a second voltage, comprising:
a first thyristor;
a first control circuit configured to control the first thyristor;
a power factor corrector circuit comprising a coil; and
a first circuit configured to convert a third voltage into a fourth dc voltage;
wherein the third voltage corresponds to a difference between a potential at a first node coupled to an output node of the coil and a reference potential; and
wherein the fourth dc voltage is configured to supply the first control circuit, and is referenced to said reference potential.
