Abstract
A power supply arrangement for an electricity meter includes an input, a full wave rectifier, and a voltage doubler circuit. The input is configured to receive a periodical input signal. The full wave rectifier is coupled to the input and has a first output. The first output is coupled to a first load of the electricity meter. The voltage doubler circuit is coupled to the input and has a second output coupled to a second load of the electricity meter. The voltage doubler is configured to prevent the flow of current from the second output to the input.
