An electric power supply system includes a rectifier with an input connected to a power line and a DC output connected to a DC / DC converter. Two buffer capacitors are connected across the input and output, respectively, of the DC / DC converter. The output of the rectifier includes a plurality of diodes. An electronically controllable switch is electrically connected in parallel with a corresponding diode of the rectifier. A controller receives an input signal from a phase voltage of the power line and provides control signals to the controllable switches. The DC / DC converter is constructed symmetrically. This configuration results in a more cost-effective power supply system with an improved energy balance.
