    • A power supply apparatus includes a coupling capacitor arranged to be connected on its first end to ground; a transformer including a primary winding and a secondary winding; a first rectifier bridge connected in parallel with the secondary winding; and an energy storage, to which a load is arranged to be connected. The primary winding is arranged to be connected between a second end of the coupling capacitor and a high voltage transmission line such that all current between the second end of the coupling capacitor and the high voltage transmission line passes through the primary winding. The energy storage is arranged to be charged by means of a current passing through the first rectifier bridge. Furthermore, the power supply apparatus includes a bypasser. A corresponding three-phase apparatus is also presented.

    • An electrical inverter with controllable output voltage comprises a three-phase self-commutated inverter bridge which is supplied from a d.c. voltage source. A reference signal generator generates a three-phase binary reference signal for controlling the shape of the curve of the output voltage of the inverter. This signal is modulated or mixed in a mixing stage with a binary pulse train having a controllable pulse-width ratio and a relatively high frequency. The output signal from the mixing stage is supplied to the inverter bridge in such a way that the output voltage of the inverter bridge corresponds to the product of the reference signal and the pulse train.

    • A DC convertor for converting power at a particular input voltage level to a higher or a lower voltage level and operable despite changes in the direction of power flux between the input and output voltage levels. Main switching thyristors operate in conjunction with turn-off thyristors, a commutation capacitor, magnetically coupled inductor windings and bypass diodes to define the magnitude and direction of the flow of current in the convertor and the voltage conversion ratio of the convertor.
