Abstract

An electrical power generating system is disclosed which includes variable voltage power supply generator means G, converter means Re3a, Re3b operable to establish a DC link by converting the variable voltage power supply to a DC voltage, voltage sensor means VSab operable to monitor the DC voltage and control means Vca, Vcb responsive to an output from the voltage sensor means and operable to maintain the DC voltage at one level. The generator means G is operable to generate two variable voltage power supplies each connected on one side to a common terminal and having an output voltage terminal on its other side, the output voltage terminal of one of the power supplies being positive and the output voltage terminal of the other power supply being negative such that the two variable voltage power supplies together comprise the DC voltage. The voltage sensor means comprises two voltage sensors severally responsive to a respective one of the power supplies, and the control means comprises two controllers Vca, Vcb severally operable to maintain the voltage of each of those power supplies at a certain level whereby to maintain the DC voltage at said one level.
