The growing interest for low power grid-tied photovoltaic systems motivates solution improvements to ensure maximum efficiency to the distributed generation process. This can be seen as a way to reduce the cost of energy production. This paper contributes to achieve an efficient and flexible solution to control a photovoltaic array by using a cascaded single-phase H-Bridge inverter. Improvement of a control strategy that ensures maximum power extraction from each H-Bridge subsystem is presented through Simulink simulations. Preliminary results will be presented to demonstrate the feasibility of the proposed distributed processing solution.

The trend for the development of more electric systems for aircrafts, microgrids, and industrial processes has been leading to the need of more efficient and reliable electronic converters. In this scenario, one can highlight the necessity of high power density rectifiers for reducing current harmonics and providing a stabilized intermediate dc-link for connection of electronic loads. Therefore, in this paper the authors present the analysis concerning the development of a novel proposal of hybrids rectifiers structures with wide range of DC voltage regulation based on Series DC Voltage Compensation Technique (SDCVC). The proposed SDCVC Technique provides voltage sag-ride through capability and assures high power density and high efficiency. In order to validated the effectiveness of the proposed solutions, preliminary modeling analysis was performed and corroborated by experimental results obtained through a 1 kW laboratory prototype of a single-phase hybrid rectifier that was put into operation under normal AC system operation, as well as under conditions of AC voltage dips.

This paper presents an ac/dc voltage doubler, where the output dc voltage is twice the input ac voltage amplitude. Two configurable power supply schemes are explored for the voltage doubler in vibrational energy harvesting applications. An `input-powered' power supply scheme eliminates standby power consumption of the circuit when the harvester is not active. Alternatively, a `cross-connected' power supply scheme reduces the minimum input voltage without additional circuit cost. Implemented in On Semi 3M-2P 0.5 μm CMOS technology, the circuit is first benchtop characterized with a signal generator and then also demonstrated with a vibrational energy harvester. A maximum power efficiency of 87% is achieved using the input-powered scheme for a 1.5 V ac input amplitude and 960 μW of output power. In the cross-connected scheme, the circuit is able to rectify input voltage amplitudes as low as 400 mV, below the transistor threshold voltage of 700 mV.

This paper presents the analysis and design of a new high frequency ac-ac converter applied to domestic induction heating. The proposed topology uses only four switches to control power. Converter operation is same as a conventional class D inverter. Working above the resonant frequency, a sinusoidal input current and a unit power factor are obtained. To bring higher efficiency and power density, application of emerging SiC technology in proposed converter has been evaluated. The analytical and simulation results have been verified by means of a 380-W induction heating prototype.

The increasing use of power electronic system has led voltage harmonic distortion level to an unacceptable level at point of common coupling (PCC). Most of the modern solutions of eliminating load current harmonics by using active filter is based on sinusoidal source voltage. However, the voltage at PCC is not purely sinusoisdal. This paper proposes a shunt active filter (SAF) based on instantaneous active and reactive power theory which can mitigate the load harmonics properly even if the source voltage is distorted. Space vector PWM based voltage source inverter is used in current control mode to filter out current harmonics. PI controllers are used for the current controller to get desired dynamic response. The proposed algorithm is verified through simulation. Real life conditions are considered in the simulation and the simulation results are presented.

A low-ripple, fast-transient, switching power converter is presented in this paper. It employs a dynamic current compensation (DCC) technique to enhance load or dynamic voltage scaling (DVS) tracking transient responses. A sensor-free, quasi-single-current-band (quasi-SCB) control is proposed to obviate the use of large-ESR filtering capacitor in conventional hysteretic control, leading to highly reduced output voltage ripples. The converter was designed with a TSMC 0.35μm CMOS process. Its input voltage can vary from 2.7 to 3.3V while the output can be regulated at any voltage level from 0.5 to 1.8V, at a switching frequency of 500kHz. Compared with its conventional counterpart, the converter achieves 153 times and 15 times speed improvement on load transient and DVS tracking, respectively.

Modern digital systems are severely constrained by both battery life and operating temperatures, resulting in strict limits on total power consumption and power density. To continue to scale digital throughput at constant power density, there is a need for increasing parallelism and dynamic voltage/bias scaling. This work presents an architecture and power converter implementation providing efficient power-delivery for microprocessors and other high-performance digital circuits stacked in vertical voltage domains. A multi-level DC-DC converter interfaces between a fixed DC voltage and multiple 0.7 V to 1.4 V voltage domains stacked in series. The converter implements dynamic voltage scaling (DVS) with multi-objective digital control implemented in an on-board (embedded) digital control system. We present measured results demonstrating functional multi-core DVS and performance with moderate load current steps. The converter demonstrates the use of a two-phase interleaved powertrain with coupled inductors to achieve voltage and current ripple reduction for the stacked ladder-converter architecture.
现代数字系统受到电池寿命和工作温度的严重限制，导致总功耗和功率密度受到严格限制。为了在恒定功率密度下继续扩展数字吞吐量，需要增加并行性和动态电压/偏置缩放。这项工作提出了一种架构和功率转换器的实现，为堆叠在垂直电压域中的微处理器和其他高性能数字电路提供高效的功率传输。多电平DC-DC变换器是在固定直流电压和多个串联堆叠的0.7 V ~ 1.4 V电压域之间的接口。该变换器在机载(嵌入式)数字控制系统中实现了动态电压缩放(DVS)和多目标数字控制。我们提出的测量结果显示功能多核分布式交换机和性能适度负载电流步骤。该变换器演示了使用两相交错动力系统和耦合电感来实现堆叠梯形变换器结构的电压和电流纹波降低。

In this paper, a novel current sensing circuit is proposed to satisfy high voltage requirement in inductor current measurement for DC/DC converters. The proposed current sensing circuit is based on Matching Complimentary Filter (MCF) technique. Besides, the novel technique uses a bootstrap circuit to cut off the approach between the sensing circuit and ground, making the supply voltage of sensing circuit floating with its input signal. The proposed scheme is verified on 35V input with 53V output DC/DC boost converter and the experimental results are presented to demonstrate the theoretical analysis. The experimental results illustrate that the proposed circuit could be applied on high voltage systems.

Energy generation through wind energy conversion systems (WECS) is expected to supply a considerable amount of electricity in the world's generation matrix. In this context, variable-speed wind turbines equipped with full-scale power electronic converters allow a WECS to be operated close to its maximum power point at each time instant. Furthermore, modern power converter guarantee high power quality, high conversion efficiency levels, reliability and flexibility. This work reviews and compares two types of modulation schemes to two novel ones that are able to drive a Δ-switch rectifier. The presented theoretical analysis is based on a WECS application. Circuit simulation and experimental results verify the operation with the considered strategies. It is shown that one of the novel sub-optimal modulation patterns presents very high performance without the need of a precise sector identification scheme.
