Designing An Open-Source Power Inverter (Part 2): Waveshape Selection

Focus:

Part 1 of this series discussed the need for an open-source kilowatt-level inverter design (dubbed the Volksinverter) and outlined a power architecture for such a design. This part 2 delves further into system design issues, explaining how battery choices influence the selection of electrical specifications for the inverter, including its power protection features. Then it reviews some mathematics relating to inverter-produced waveshapes, which will help later in optimizing inverter design to meet various design goals. But first, the author notes the similarity between inverters and another power supply function—power factor corrected battery chargers to help us understand the origins of certain inverter design equations.

What you’ll learn:

• How to understand how battery choices influence inverter specifications
• How to understand how inverter output waveshapes affect inverter performance and design choices
