Patent ID: 8270188

Claim:
A power supply, comprising: a three-phase power source configured to provide three alternating current (AC) voltage signals; a capacitor divider circuit, coupled to the three-phase power source, configured to generate three disparate AC voltage signals, wherein an amplitude of the three AC voltage signals is higher than an amplitude of the three disparate AC voltage signals, and wherein the capacitor divider circuit includes a pair of capacitors coupled between a first output line of the three-phase power source and at least one of a neutral line or a second output line of the three-phase power source; a main power supply coupled to the three-phase power source and including a first set of capacitors configured to reduce electromagnetic interference (EMI) noise; and an auxiliary power supply including a second set capacitors, wherein, the pair of capacitors of the capacitor divider circuit includes one capacitor from the first set of capacitors coupled in series with one capacitor from the second set of capacitors, wherein the capacitor divider circuit is configured to decrease the voltage level of a three-phase alternating current (AC) power waveform provided by the three-phase power source.
