Inverter Breakout Board

Project Overview

My second PCB project for Mozee Motorsports. My initial goals was to allow communication via CAN to our new inverter, the Cascadia Motion PM100DX-SP. Two main connectors were used that attach to the inverter, and some breakouts are added to facilitate ease of use.

Revision One – CAN Only

The first revision of this project was to control the inverter entirely through CAN. Most of the components on this schematic help facilitate the ease of use for the inverter, as well as provide connections to necessary pins.

Revision Two – CAN to Analog Converter

Revision two includes the CAN to Analog Converter schematic. The goal of this second revision was to include both a CAN only mode or a mode that converts signals from the Hybrid Control Board (HCB), or the vehicle’s controller, to analog signals for the inverter.

This revision was quite more complex than the previous one, due to having a microcontroller, the STM32G4. Due to the added complexity, a four layer pcb layout was used in place of the two layer layout the previous revision had. The two added layers were for ground and +3.3V.
