High performance deadbeat controlled PWM inverter using a current source compensator and nonlinear loads
Abstract -- A new control technique which
generates high-quality sinusoidal output voltage
from a single-phase PWM inverter suitable for
the UPS system is presented. A scheme for
combining the deadbeat control with a current
source compensator is proposed, and the control
mechanism is analyzed. A current source
compensator is used to compensate the voltage drop
at the firing instant of a triac controlled resistive
load. The PWM is determined at every sampling
instant by the proposed new algorithm. Simulation
results show that the proposed scheme can produce
nearly sinusoidal waveforms for nonlinear loads.
