A Low-Voltage Three-Phase AC Generator Built from Analogue Blocks
Authors: Francisco Llopis, Jacobo González, Mario Jakas
Abstract: A circuit capable of delivering three 40Vpp 50Hz AC voltage outputs with 120º phase separation between them has been built. It uses standard, low-cost electronic components and, unlike other previous similar power supplies [1-3], the present circuit is entirely based on analogue electronics. This power supply was purposely built for educational purposes, where low-voltage is necessary in order to prevent students from suffering electrical shocks. Its design, simple and robust, makes this circuit be an interesting project for undergraduate students, either as part of a regular electronics laboratory course or as a final degree project in electronic and electrical engineering.
