| Abstract |
Three-phase PWM rectifiers are becoming increasingly popular as the front-end converter unit in
power electronic systems due to tighter EMC regulations. In this paper the three-phase current-type
dc-voltage source with reactive power control is introduced. When the control system is realized in
the supply-voltage-oriented reference frame the active (the dc-link voltage) and reactive power can be
independently controlled with real and imaginary axis components of the supply current vector
respectively. It is also shown that in synchronously rotating coordinates, where the sinusoidal
variables appear as dc quantities, the compensation of the reactive power drawn by the supply filter
can be done very easily. The proposed control system is realized using a single-chip Motorola
MC68HC916Y1 microcontroller. Some experimental results are also shown. |
