Abstract
An example polarity inverter includes multiple contactors, each of which includes switches that are controllable to configure a current path. Each of the multiple contactors includes contacts, which are interleaved such that first contacts to receive voltage having a first polarity alternate with second contacts to receive voltage having a second polarity, where the first polarity and the second polarity are different. The polarity inverter also includes a first conductive plate to connect electrically to each of the first contacts, and a second conductive plate to connect electrically to each of the second contacts. The first conductive plate and the second conductive plate are in parallel. A dielectric material is between the first conductive plate and the second conductive plate.
