Abstract

An electric power converter combination converts AC power from a main AC supply network (1) to DC power to supply a DC load (2), the converter combination comprising a phase controlled thyristor supply bridge rectifier (4) and an auxiliary PWM converter (10) connected across a DC output filter (8) of the thyristor supply bridge (4), the auxiliary PWM converter (10) also being connected to a power supply comprising either the main AC supply network (1), an AC supply independent of the main AC supply network, or a low voltage DC supply.
