I would like to start by thanking my examiner and supervisor Dr. Stefan Lundberg for all the help I have received during the project. Despite your high workload you always. The hardware designed in the project will be based on initial calculations and simulations. All parameters are not possible to simulate.

This project presents a design and construction of a three-phase inverter, drive circuit and dc-link capacitor bank. The inverter should be able to supply an electrical machine with 48 V and 250 A. Initial calculations and simulations were made to get some base for the ordering of hardware.
What is a reference design for a 3 phase inverter?
This reference design reduces system cost and enables a compact design for a reinforced, isolated, 10-kW, three-phase inverter. A lower system cost and compact form factor is achieved by using a dual gate driver in a single package and bootstrap configuration to generate floating voltages for the gate drive power supply.
What is an Arduino 3-phase inverter?
A circuit that uses a programmable Arduino-based oscillator to generate a three-phase AC output is known as an Arduino three-phase inverter. In order to operate a specific three-phase load, we may learn how to build a basic Arduino-based microcontroller three-phase inverter circuit in the following section.
The printed circuit board (PCB) for the inverter is made on a board with thermal substrate technique, meaning that the board consists of an alu-minum plate with a thin dielectric layer on one of the sides. Over the Table 3.2: MOSFET parameters. dielectric layer there circuit layer is located.
Are MOSFETs safe for 3 phase inverter circuits?
As we all know MOSFETs used in three-phase inverter circuits can be quite susceptible to damage due to various risky parameters that come into play with these concepts. This is especially true when dealing with inductive loads.
How do inverter PCBs work?
The inverter PCBs are mounted on an aluminum frame where liquid runs between them to cool the inverter. The drive circuit is controlled with a dSPACE system and the tests are made with a load consisting of cables and iron powder cores. Temperatures are measured with PT100 sensors for the water and an infrared camera for the surfaces.
