Adaptive piezoelectric energy harvesting circuit for wireless remote power supply
IEEE Transactions on Power Electronics - Tập 17 Số 5 - Trang 669-676 - 2002
This paper describes an approach to harvesting electrical energy from a mechanically excited piezoelectric element. A vibrating piezoelectric device differs from a typical electrical power source in that it has a capacitive rather than inductive source impedance, and may be driven by mechanical vibrations of varying amplitude. An analytical expression for the optimal power flow from a rectified pi...... hiện toàn bộ

Novel zero-voltage and zero-current-switching (ZVZCS) full-bridge PWM converter using coupled output inductor
IEEE Transactions on Power Electronics - Tập 17 Số 5 - Trang 641-648 - 2002
A novel zero-voltage and zero-current-switching (ZVZCS) full-bridge pulse-width-modulated (PWM) converter is proposed to improve the previously proposed ZVZCS full-bridge PWM converters. By employing a simple auxiliary circuit with neither lossy components nor active switches, soft-switching of the primary switches is achieved. The proposed converter has many advantages such as simple auxiliary ci...... hiện toàn bộ

A novel suppressed-link rectifier-inverter topology with near unity power factor
IEEE Transactions on Power Electronics - Tập 17 Số 5 - Trang 692-700 - 2002
This work describes a novel method in improving the input current total harmonic distortion (THD) as well as the power factor of a three-phase suppressed-link rectifier-inverter circuit. This proposed method makes use of only three bi-directional low power static switches with a relatively simple gating circuit. This paper illustrates how the proposed method is superior in reducing the input curre...... hiện toàn bộ

Unified steady-state analysis of soft-switching DC-DC converters
IEEE Transactions on Power Electronics - Tập 17 Số 5 - Trang 684-691 - 2002
In this paper, based on the switching cell approach, a unified steady state analysis for families of soft-switching DC-DC converters with complete unified design equations will be presented. The concept of the unified approach and step by step procedure for a generalized process are discussed and applied to selected soft-switching families such as zero-voltage-switching (ZVS) and zero-current-swit...... hiện toàn bộ

Single current sensor control for single-phase active power factor correction
IEEE Transactions on Power Electronics - Tập 17 Số 5 - Trang 623-632 - 2002
This paper presents the realization of a boost-type active power factor corrector (APFC) using a single current sensor to sense the inductor current for input current shaping and output voltage regulation. Neither input voltage nor output voltage sensing is needed. The sensed inductor current is used for two main functions. The first one is for comparing with a sawtooth signal in order to shape th...... hiện toàn bộ

Priority-Driven Self-Optimizing Power Control Scheme for Interlinking Converters of Hybrid AC/DC Microgrid Clusters in Decentralized Manner
IEEE Transactions on Power Electronics - Tập 37 Số 5 - Trang 5970-5983 - 2022
Hybrid ac/dc microgrid clusters are key building blocks of smart grid to support sustainable and resilient urban power systems. Practically, in networked microgrid clusters, the subgrid load-priorities and power quality requirements for different areas vary significantly. In order to realize optimal power exchanges among microgrid clusters, this article proposes a decentralized self-optimiz...... hiện toàn bộ
