A Study on the Current Characteristic of Full Bridge Series Inverter

The application of A.C. motor as'servomotor is rapidly increased with the recent advance of power electronics and digital control methods. The induction motor which has a simple structure and needs less maintenance is used in the industrial field for the variable speed and position control. In this paper. the current characteristics of the system composed of R.L.C. load and series bridge inverter is investigated through the results of computer simulation and experiment to look for the good properties of A.C. motor driven by the above inverter. The time schedule of conventional bridge inverter and the parameters such as resistance and damping coefficient of load is changed for good results. It is possible to get the load current of similar sine wave under various conditions.
