The QSGs also offer attenuation to harmonics and dc-offset present in the sensed input voltages. Fourth-order QSGs offer superior harmonic attenuation with complete dc-offset rejection compared to lower-order QSGs. Therefore, dual fourth-order QSG + PSC is an apt solution for pre-filtering in phase-locked loops (PLLs) under non-ideal grid voltage conditions. Two fourth-order QSGs (FO-QSGs) namely, second-order SOGI-QSG (SO-SOGI-QSG) and cascaded SOGI-QSG have been proposed in the literature. Parameter selection for these FO-QSGs to achieve a faster dynamic response is challenging due to the higher order of the transfer functions. The response time of the QSGs directly impact the response time of the PLL. This paper proposes a new approach to fourth-order quadrature signal generation that achieves a lower settling time for the QSG compared to existing FO-QSGs. The proposed method achieves a faster response time by setting the QSG parameters using equations that directly relate to the system settling time. Using the proposed method, the QSG settles within 25.4 ms while maintaining a low total harmonic distortion. INDEX TERMS Phase-locked loop, non-ideal grid, second-order generalized integrator, quadrature signal generator.

The QSG’s order directly impacts the dynamics and quality of the generated positive sequence component. Fourth-order QSGs have better filtering capability when compared to second-and third-order QSGs. They exhibit superior performance in the presence of harmonic distorted grid voltages. However, the dynamic response of such fourth-order QSGs are greatly affected by the choice of system parameters. In this paper, an analytical approach based on settling time is proposed for parameter selection of two existing second-order generalized integrator (SOGI) based fourth-order QSGs viz. cascaded SOGI-QSG and second-order SOGI-QSG (SO-SOGI-QSG). The proposed method predicts the settling time for a choice of parameter selection with better accuracy than the existing procedure. It also helps in choosing parameter values that lead to faster settling times. Simulation and hardware results are provided to support the proposed approach.

A careful design of the gate driver is essential for reliable converter operation. Gate resistor selection and isolation between the power and control circuit are of primary importance. Gate drivers are also expected to offer protection like Active Miller clamp (AMC), soft turn-off, short-circuit detection and under-voltage lockout. In this paper, a comprehensive design and selection of components for the various control and protection aspects of a 10kVA IGBT inverter gate driver is presented. The gate driver is built around ACPL-333J optocoupler IC. The protection schemes are discussed along with the inverter structure for better insight and design. A novel method of gate driver selection based on fracdidt\frac{{di}}{{dt}}fracdidt provided in the device datasheet is proposed to balance between switching speed and reduced EMI. The proposed method results in a simple analytical expression for gate resistor selection. With the selected gate resistor the device fracdidt\frac{{di}}{{dt}}fracdidt is obtained same as the datasheet value and is validated experimentally. Important aspects related to selection of an on-board integrated isolated power supply and printed circuit board (PCB) design considerations are also presented. Hardware results are provided for the discussed protection schemes.

However, despite the first practical use of silicon based solar cell more than 50 years ago, it has not been exploited to its full potential due to the high cost of electrical conversion on a per Watt basis. Many new kinds of photovoltaic cells such as multi-junction solar cells dye-sensitized solar cells and organic solar cell incorporating element of nanotechnology have been proposed to increase the efficiency and reduce the cost. Nanotechnology, in the form of quantum dots, nanorods, nanotubes, and grapheme, has been shown to enhance absorption of sunlight, makes low cost flexible solar panels and increases the efficiency of photovoltaic cells. The chapter reviews the state of current photovoltaic cells and challenges it presents. It also discusses the use of nanotechnology in the application of photovoltaic cells and future research directions to improve the efficiency of solar cells and reduce the cost.
