Systems and methods for galvanic isolator with printed circuit board

Abstract

A system includes an inverter configured to convert DC power from a battery to AC power to drive a motor, wherein the inverter includes: a galvanic isolator separating a high voltage area of the inverter from a low voltage area of the inverter; a low voltage controller in the low voltage area; and a high voltage controller in the high voltage area and configured to communicate with the low voltage controller via the galvanic isolator, wherein the galvanic isolator includes: a printed circuit board (PCB) including a substrate having a high voltage side defining the high voltage area and a low voltage side defining the low voltage area, a low voltage metal trace on the low voltage side of the substrate and connected to the low voltage controller, and a high voltage metal trace on the high voltage side of the substrate and connected to the high voltage controller.
