Patent ID: 6977445

Claim:
A rectifier circuit for powering three power conversion modules using a three phase AC input without a neutral connection, said rectifier circuit comprising: a first bridge rectifier that is connected to a first phase of said three phase AC input and that produces a first rectified waveform; a second bridge rectifier that is connected to a second phase of said three phase AC input and that produces a second rectified waveform; a third bridge rectifier that is connected to a third phase of said three phase AC input and that produces a third rectified waveform; and a first inductor having one end that is connected to said first bridge rectifier; a second inductor having one end that is connected to said second bridge rectifier; and a third inductor having one end that is connected to said third bridge rectifier, wherein opposite ends of said first, second and third inductors are connected to form a virtual neutral.
