An alternating current AC to direct current DC converting circuit for a turbine generator is provided that comprises an active AC/DC converter having a controllable output voltage level having an input for receiving alternating current electrical power from a turbine generator and an output for providing direct current electrical power to an electrolysis system for electrolysis of water. The AC to DC converter further comprises an oscillator for generating an alternating current auxiliary signal and a summation circuit for adding the alternating current signal to the output of the active AC DC converter. By adding an AC component to the DC output of the active AC DC converter, electrolysis cells in the electrolysis module connected to the AC DC converting circuit have been proven to operate more efficiently. The amplitude of the alternating current auxiliary signal is preferably less than the output voltage of the active AC/DC converter.
