Abstract :
A fixed-frequency 360-Hz SCR inverter operated with an inductive and three-phase motor load is described. Such an inverter could provide a solid-state motor control more compact and possibly at a lower cost for a given horsepower than a 60-Hz system. A McMurray-Bedford inverter circuit was used similar to that described by Bedford and Hoft in [1]. The inverter operation has been described in detail by an approximate equivalent circuit approach for which a digital computer simulation was devised. Computer plots of various waveforms and experimental results are included. This simulation gives a thorough prediction of the circuit behavior with inductive load. The circuit provides a reliable and efficient ac power source with a fixed frequency. An accurate prediction by the digital computer simulation enables one to choose most efficiently. circuit elements which would perform the function most efficiently.
