A system and method for converting a relatively high voltage into a relatively low voltage, the method comprising the steps of: receiving a first series of pulses at the relatively high voltage and a first frequency; and converting the first series of pulses into a second series of pulses at a second voltage lower than the relatively high voltage and a second frequency higher than the first frequency. The first series of pulses may be a waveform and the converting step may be triggered by the waveform of the first series of pulses exceeding the relatively low voltage. The first series of pulses may be direct current pulses and the receiving step may comprise receiving an alternating current voltage and rectifying the alternating current voltage into the first series of pulses. The second frequency may be some multiple of the first frequency, such as twice the first frequency.
