Project overview

Wi-Fi enabled power control board with five high-voltage relays and a motor driver output for pump and load control, built for renewable energy and water system integration.

Engineering approach

Power electronics work lives or dies on thermal design and conversion efficiency, with layout decisions directly affecting how much heat a board has to shed. On this board, that translates into a component set built around ESP32 and 5x High-Voltage Relays, with layout and stack-up decisions driven by power conversion efficiency, thermal management, and accurate current and voltage sensing.
