A method and apparatus for controlling the feed rate of a rectified AC pulses via a gated rectifier in a low DC voltage and current power supply. The gated rectifier outputs gated AC pulses to an input capacitor via a current control diode and/or a zener diode and/or a resistor for charging the input capacitor to a voltage level and a charge capacity commensurate with the low voltage regulator and the low DC current drain.A gate capacitor for accumulating incremental charges of rectified AC pulses fed via a divider network is pre-configured to trigger the gated rectifier, timed by discharging the aggregated charge of a predetermined number of charges to the gate.The input capacitor charged by the gated AC pulses at a rate of one per said predetermined number to the input capacitor feeds the voltage regulator for powering a low DC current consuming device.The power supply further includes a timer or a CPU for accurately triggering the gated rectifier, after the initial DC power is ready to feed DC to the timer or the CPU. When the CPU is powered it can change the triggering time commensurate with the current drain.
