Load current observer based feed-forward DC bus voltage control for active rectifiers - Petar Igic (Electric Power Systems Research, 2012)
A load current observer based feed forward control scheme for three-phase voltage source pulse width modulation (PWM) active rectifiers is developed. This provides a control solution for fast dc bus voltage control without measuring dc link load current and results in a reduction of cost required for the current sensors. In additional to the fast current control technique developed, a method of estimating dc link capacitance is also developed and verified using simulation program. Test results were illustrated at the end of the paper. The journal's impact factor in 2012 is: 1.481
