Abstract
Three phase PWM inverters employing flux regulators have been shown to be a superior means of control
for distributed UPS systems and other applications. However, in most manifestations, they have the
drawback of variable switching frequency. In this paper, a flux regulator operating at constant switching
frequency is presented. The regulator operates in the synchronously rotating d-q frame of reference, and
uses a proportional controller with decoupling between D and Q axis quantities. The flux regulator is used
as a basis for output voltage of a sinusoidal inverter system. Analytical results with computer simulations
verified using an experiment prototype inverter are presented in the paper. |
