“…The bus voltage controller is not the critical part of the control of the VSI because balancing the input and output power is a slow process and the (large) capacitor at the dc-bus serves as a buffer. Therefore it is justified that little attention is paid to the design of this bus voltage controller which can be seen in literature [1][2][3][4][5][6][7][8][9][10]. However this controller can (negatively) influence the behaviour of the VSI.…”

“…Another aspect of the bus voltage controller is the timing of updating the output. The output of the bus voltage controller can be synchronised with the zero-crossings of a phase voltage [1][2][3][4][5][6][7][8][9][10]. This method will result in a step in the amplitude in the other two phases of the injected current if the output is changed due to a transient in the power balance.…”

“…The interaction can result in harmonics in the injected current. The bus voltage controller is usually a PI-controller with a randomly chosen sample frequency [3], [12][13][14][15]. The sample frequency is usually chosen low in order to reduce the effect of ripple on the bus voltage.…”

An important function of the bus voltage controller of voltage-source inverters (VSI) for distributed generation (DG) applications is to control the balance between ac and dc power. Nevertheless is the bus voltage controller not the critical part of the control of the VSI. Therefore it is justified that little attention is paid to the design of this bus voltage controller what can be seen in literature. However, this controller can (negatively) influence the behaviour of the VSI. In three-phase systems a ripple can exist in the bus voltage due to unbalance or harmonics present in the grid voltage or current. This ripple can interact with the bus voltage controller which can have negative consequences on the injected current. Also the timing of updating the output of the bus voltage controller can have consequences on the waveform distortion which can result in oscillations. In this paper the focus is on the timing of updating. An overview of three possible bus voltage controllers is given. The response of the different implementations of dc-bus voltage controllers during a transient is simulated.

Abstract-This paper describes Shunt Active Power Line Conditioners (APLC) for compensating harmonic currents and reactive power drawn by the non-linear loads besides power factor correction. The shunt APLC is implemented with three phase PWM current controlled voltage source inverter and is connected at the point of common coupling (PCC) for compensating the harmonics. The compensation process is based on phase locked loop (PLL) synchronization with proportional integral derivative (PID) controller. These control strategies for shunt APLC makes certain that source current is sinusoidal even when the load is non-linear and unbalanced. The PWM-VSI inverter switching is done according to gating signals derived from hysteresis band current controller (HCC) and the capacitor voltage is maintained constant using PID controller. The proposed shunt APLC is investigated using extensive simulation and is found to be effective in terms of THD, reactive power compensation and VDC settling time under various balanced and unbalanced load conditions.

“…To overcome these drawbacks pulse width modulation (PWM) AC-DC converters are used, which effectively regulate the output DC voltage and have a low value of THD. The PWM AC-DC converters have the capability of bi-directional power flow, unit power factor, low THD and a regulated DC voltage at the output [1][2][3]. To regulate the operation of three phase PWM AC-DC converters, proportional integral (PI) and proportional integral derivative (PID) controllers are commonly used.…”

Abstract. This paper discusses control strategy for the voltage regulation of a three phase pulse width modulation (PWM) AC-DC converter. A fuzzy logic controller (FLC) is employed in the outer voltage loop. Fuzzy logic controllers are preferred over the conventional proportional integral (PI) controllers because they are based on linguistic description and do not require a prior mathematical model of the system. The objective of the presented control system is to regulate the output DC voltage during both transient and steady state period. Also the line currents drawn from the grid should be sinusoidal and in phase with respective phase voltages to achieve a low total harmonic distortion (THD) and unity power factor. PI and FLC based control systems are implemented for three phase PWM AC-DC converter in MATLAB/Simulink and dynamic performance of the system is tested. The results demonstrate that compared to the conventional PI, the FLC based system is more robust and has a much better dynamic response. The low value of THD and sinusoidal current response ensures the system avoids polluting the utility grid.
