Abstract: A power system including a rectifier and an inverter. The rectifier has a plurality of phase input terminals and a plurality of rectifier output terminals that provide respective rectified outputs, rectifier circuitry that rectifies the signals on the phase input terminals to generate respective rectified outputs on the rectifier output terminals, a rectifier neutral to receive a power source neutral, and capacitors connected between the rectifier neutral and the rectifier output terminals. The inverter includes a respective plurality of inverter input terminals respectively connected to the rectifier output terminals, a plurality of inverter output terminals, and an inverter neutral. The rectifier neutral and the inverter neutral are coupled by a conductor to form a same neutral.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for non-isolated power conversion. In one aspect, a method includes generating first and second rectified outputs using a rectifier with a first input and a second input connected respectively to a first and second output of a power source, capacitively coupling the first and second rectified outputs to a neutral, generating first and second AC outputs from the first and second rectified outputs, and capacitively coupling the first and second AC outputs to the neutral. Other embodiments of this aspect include corresponding systems, apparatus, and computer programs, configured to perform the actions of the methods, encoded on computer storage devices.
