| Abstract |
Now days an active power filters are very important way to increase power quality due to use of various nonlinear loads. This paper presents the active filtering function for PWM rectifiers. Since active power filters are no indispensable and total cost of power quality compensator can be lower. The control algorithm is based on ac line voltage sensorless Direct Power Control with constant switching frequency. Two various schemes, closed and open loop control are presented. The operation of the system is investigated in simulations using SABER package and experimentally verified using laboratory setup based on commercial Danfoss inverter. Obtained results fully confirm suitability of PWM rectifier integration together with power quality compensator. This system improves the supply current harmonic content, power factor displacement and serves as active rectifier for drives and other dc-link loads. |
