Abstract :
A DC/AC inverter system is described. The device uses a 3-phase ferroresonant power transformer, constructed on a single 3-leg magnetic core, to supply an isolated balanced 3-phase output voltage with variable balanced or unbalanced loads. Test results indicate that the single 3-leg core transformer arrangement performs as well as a dual-core arrangement and requires less time to assemble and install. It is concluded that the single-core 3-leg ferroresonant design is a practical and cost-effective way to construct an inverter transformer
