<p>An alternating current electrical power supply circuit comprises a rectifier adapted to be connected to an AC mains supply. It produces a rectified output voltage including ripple. An amplifier-inverter has power supply terminals connected to the output of the rectifier. A voltage including ripple synchronous and in phase with the voltage of the AC mains supply is applied to a control input of the amplifier-inverter.</p> |
