Abstract

This paper presents the performance of capacitor-charging-type inverters. Both single- and three-phase inverters are considered. A simple technique to design the L -C elements of such an inverter is introduced. The switching devices are operated in the discontinuous conduction mode to reduce the size of the inductor and also for better dynamic performance. The inverter is simulated in PSPICE. An experimental prototype is produced to verify the results from simulation. Experimentations have been conducted for single-phase and three-phase systems. The inverter is found to operate satisfactorily for various types of load including unbalanced load.
