“…Accompanying significant increase of IGBT transistor performance during the last decade allows to obtain successful implementation of PWM boost AC-DC three phase converter topology in many applications where harmonic distortion emission has to be limited. PWM boost type AC-DC converters, besides line current harmonic distortion significant reduction in frequency range up to 2 kHz, have also other advantages [19], [20], [21], like for example:…”

Modern AC/DC converters with bidirectional power flow employing PWM boost topology generate harmonic distortions of input current in relatively high frequency range tightly related to modulation carrier frequency. These frequencies and its multiples in typical applications are usually located in frequency range from single up to several of kHz. Increased harmonic emission in this frequency range can easily and harmfully influence sensitive control and measurement systems what occurs more often nowadays in applications where high power AC/DC PWM boost converted are used. This paper presents a comparison of current harmonic emission of PWM boost rectifiers with relation to classic diode rectifiers. New class of electromagnetic compatibility problems arising in power system are underlined as a result of increased harmonic distortions emission in frequency range up to 9 kHz.

“…All of these works claims to obtain an improvement in the performance of the rectifier with compensation functions. Other works are focused in the use of estimators to reduce the number of voltage and/or current sensors in the power converter [6]. However, previous works do not includes a study about the effect of the incorporation of active filter function over the PWM-VSR-C, such as, reactive power generation capability, impact over the apparent power, dc bus voltage requirements, raising of temperature on IGBTs due to losses, etc.…”

This work claims to identify the possible problems and limitations caused for the inclusion of the active filter function in a three phase PWM rectifier (PWM-VSR-C). Basically, the following topics are covered: the study of the PWM-VSR-C as a reactive power source, calculations of apparent power and dc bus voltage requirements, a study about the electric system around the PWM-VSR-C and the variation of the losses, due to the inclusion of the active filter function. Experimental work is included to validate the main results.

“…In recent years, PWM rectifier gets more and more widely used because of its many advantages such as low current harmonic distortion, high power factor and stable DC side voltage [1]. Common control strategy of PWM rectifier is Vector Control (VC), which realizes decoupling control and fixed switching frequency.…”

In PWM rectifier control strategy, Direct Power Control (DPC) has been used more and more widely in order to solve the problem of complex rotating coordinate transformation of Vector Control. Traditional DPC method with variable switching frequency is applied based on instantaneous power theory and switching table. This approach requires more voltage and current sensors to calculate active and reactive power, leading to low anti-jamming capability. And the use of bang-bang control results in large power fluctuation. For these problems, an improved DPC strategy with fixed switching frequency is proposed based on virtual flux and Space Voltage Modulation (SVM). This method simplifies the circuit structure by omitting the voltage sensors and obtains continuous control by SVM instead of switching table. A comprehensive theoretical analysis of two DPC methods above is given and the comparison of simulation results is presented in Matlab/simulink. The simulation results show that DPC based on virtual flux and SVM has better dynamic and static control performance.
