Abstract: Fast control DC-link voltage is the key to enhance Low-Voltage Ride-Through (LVRT) for the Permanent Magnet Synchronous Generator (PMSG). When grid voltage dips deeply, by the constraint of the capacity of the grid-side converter and reactive power support by the grid-code required, the active power capacity of the grid-side converter will be reduced. Therefore, it cannot stabilize th...

Reactive power control can control voltage within the proper range from the power network side or from the distribution generation (PV (photovoltaic)) side. Reactive power control from the power network side is simpler because little controlled object apparatus, such as STATCOM, is required. However, it is difficult to optimize the individual voltages of residential consumers because few data h...

Neutral-point-clamped pulsewidth modulation rectifiers (NPCR’s) are suitable for high-voltage systems because of their circuit structure. The NPCR’s, however, have a problem, in that the neutral point potential (NPP) varies when the current flows into or out of the neutral point. The variations cause voltage deviations in the input waveforms, as well as unbalanced voltage stress on the devices....

Voltage regulator modules (VRM) need to have low output voltage ripple and tight efficiency power advanced microprocessors.

The control scheme suitable for applications such as ...

This paper deals with the problem of interfacing a wind turbine generator with an electrical three phase grid in the presence of nonlinear loads. Wind systems are generally connected to the grid through an AC/DC inverter in the generator side, followed by a DC/AC converter in the grid side. In this work, the considered DC/AC converter is based on multilevel neutral point clamped topology, and w...

This article reviews a new technique for secondary side control of a DC-DC converter without using an auxiliary bias supply. A unique primary side start up circuit is used to drive the primary side power transistor. Gate pulse information for the primary transistor is transmitted through a pulse transformer that is shown to be smaller than an opto-isolator. The discussion includes transformer-r...

A new very simple single phase ac-ac voltage regulator based on LC network is proposed here that compensates wide range supply voltage variations. This has the capability of both buck and boost the input source voltage level without any change of phase angle. The number of components used in the converter circuit is minimum and smooth output waveform can be achieved without any additional filte...

By adopting the technique of pre-regulator, a high PSRR and low temperature coefficient piecewise-linear bandgap reference (BGR) is designed for analog and mixed-signal application in this paper. The piecewise-linear BGR with pre-regulator, which is analyzed and simulated in SMIC 0.18μm CMOS process, has simple circuit architecture. Simulation results show that piecewise-linear BGR with pre-reg...
