TL;DR: A novel current link topology with a diode rectifier and magnetic energy recovery switch (MERS) using a current source inverter for offshore-wind-farm application and experimental results represent the effectiveness of the topology.
Abstract: This paper proposes a novel current link topology with a diode rectifier and magnetic energy recovery switch (MERS) using a current source inverter for offshore-wind-farm application. Despite the use of a diode rectifier, the proposed topology is capable of regulating individual turbine torque partially. Because offshore wind condition is more stable and has less turbulence intensity (typically 0.08) than that of onshore wind, the individual full-range controllability realized typically by pulse-controlled converters is not necessary. Instead of them, the proposed scheme, a diode rectifier with MERS, has only partial controllability of the individual generator torque which is estimated to be sufficient to achieve the maximum power point tracking operation for offshore-wind-farm application. The proposed topology is aiming to be applicable for offshore wind farms where maintenance reduction is conclusively a critical issue because of the inaccessibility. In this paper, experimental results represent the effectiveness of the topology. Moreover, a new control strategy for offshore wind farms with the proposed topology is also proposed.

TL;DR: In this paper, a new rectifier controlled by predictive instantaneous-current PWM control schemes for reducing AC-side harmonic currents in consideration of the DC-side voltage ripple is proposed.
Abstract: A new rectifier controlled by predictive instantaneous-current PWM control schemes for reducing AC-side harmonic currents in consideration of the DC-side voltage ripple is proposed. Unity power factor is also obtained. The paper describes three control schemes for a single-phase rectifier, and experimental and simulation studies of rectifier performance. The effectiveness of the control schemes is confirmed by experiments and simulations. The rectifier can be used in applications such as UPS systems and static VAr compensators. >

TL;DR: In this article, a plurality of diodes and a silicon controlled rectifier are connected in series across the output of the power supply, triggered by a predetermined transient voltage level.
Abstract: Apparatus for protecting electrical circuitry from voltage transients in a power supply or the like connected to the circuitry. A plurality of diodes and a silicon controlled rectifier are connected in series across the output of the power supply. The silicon controlled rectifier is triggered by a predetermined transient voltage level, and the output voltage of the power supply is clamped at the sum of the forward voltage drops of the diodes and controlled rectifier, the sum being set above the normal output voltage level of the power supply. The silicon controlled rectifier then commutates as soon as the transient ceases and the voltage level drops to normal. Various configurations are provided for DC or AC systems, as well as for remote sensing, and additional compensating circuits are employed for various applications.

TL;DR: In this paper, a rectifier circuit with a first MOS transistor, a second MOS transistors, and a second switching circuit for supplying a bias voltage to the first transistor in response to a control signal is described.
Abstract: A rectifier circuit includes a first MOS transistor; a first capacitor connected between a gate and a source of the first MOS transistor; a first switching circuit for supplying a bias voltage to the first capacitor in response to a control signal; a second MOS transistor whose drain is connected to the source of the first MOS transistor; a second capacitor connected between a gate and a source of the second MOS transistor; and a second switching circuit for supplying the bias voltage to the second capacitor in response to the control signal. The rectifier circuit also includes a third MOS transistor for imitating the first MOS transistor; a third capacitor for imitating the first capacitor; a dummy switching circuit for supplying the bias voltage to the third capacitor in response to the control signal; and a generating circuit for generating the control signal based on a potential of the third capacitor.
