“…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.…”

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.

“…Although complete harmonic compensation is only possible using true active filters [12], it has been shown [9]- [11], [13], [14] that shunt active compensators, behaving as linear resistive shunt harmonic impedances (SHI) for harmonics, can provide a considerable reduction of the harmonic propagation throughout a distribution feeder. A good choice to install a resistive SHI is near the end of the feeder [15], which confirms the proposition suggested by Akagi [9], [13], [16] to place an active line terminator on the distribution feeder with a resistive impedance behaviour for harmonics.…”

“…The resistive impedance function can be implemented as the control objective of an active (power electronic) compensator [8], [9], [13], [16] or as a secondary function of an active power supply [2], [7], [11], [17], [18]. This may be achieved by proper design of the control strategy.…”

“…A comparable control strategy is also introduced by [11] for three phase ac-dc converters. Nevertheless, this control strategy (using the p − q transformation) is not (easily) applicable to single-phase converters (low power applications), so the new control strategy proposed in this paper is based upon the control of [17], [23].…”

Abstract-The amount of non-linear and unbalanced loads (such as adjustable speed drives and PC's) connected to the electric power system is steadily growing. The power quality i.e. the reliability of the energy supply and the quality of the voltage waveform, may be severely degraded and may cause many unfavourable effects on both the power system and the connected loads. Especially in the case of resonances, severe voltage distortion may result. Although complete compensation is only possible using true active filters, resistive shunt harmonic impedances (SHI) have been shown to provide a considerable reduction of the harmonic propagation. These impedances can be implemented using active power electronic devices and are controlled to synthesize a resistive load. Benefits: no need to measure the polluting load current, effective for all harmonics and different resonance conditions, simple control strategy, and may be implemented as a secondary control function of an active power supply.In this paper, a practical implementation of a resistive SHI is proposed. A new control strategy for a boost power factor correction (PFC) converter has been implemented in order to achieve a programmable resistive input impedance for harmonics, independent of the input impedance for the fundamental component. Furthermore, the potential to damp a resonance in a power distribution system is demonstrated using an experimental setup.
