A compact and comprehensive micro-electronic control system for an unorthodox inverter-converter
Abstract
Presented is an approach for the use of field effect transistors in a free running parallel inverter-converter. An attempt is made to reconcile the limitations, which are imposed by the speed of operation of the control electronics and of the concerned magnetic elements with the increased demands imposed by the severe di/dt's of the field effect transistors; the magnetic components and the associated control electronics are so devised as to handle the new demands. The difficulties of a dual type over-current protection are presented. Avoided is exceeding of the maximum instantaneous as well as the maximum average current. The presented concept is illustrated with the tests and results of an experimental model operating at 50 kHz. The potential of higher frequencies of operation appears indicated.
