This paper present a sliding mode control operating at fixed switching frequency for a three-phase unity power factor rectifier using the vector operation technique. The proposed method allows to find a large-signal converter dynamic model in order to transform a tree-phase system into two decoupled subsystems. With this technique only two sliding-mode controllers are needed and the neutral point...
This paper presents a novel compact on-chip voltage-controlled two-state inductor design for use in high-frequency RF circuits. This inductor design can be used in multiple-band passive matching networks, VCO LC tank circuits, or as controllable phase delay units. Simulations of a single-turn spiral inductor design show a controllable 76% increase is possible between the "low" and "high"...
This paper is concerned with the design and simulation of a pulse width modulation (PWM) rectifier for three-phase Permanent Magnetic motor drive. Based on the mathematical model of PWM rectifier, the dual-close-loop engineering design with decoupled feed-forward control is applied in the 3-phase voltage source rectifier. The objective to be reached is to realize unity power factor at the input ac...
Classical 3-phase inverters cannot produce AC voltage with the magnitude greater than DC input voltage. For an approach a DC-DC boost converter should be used between the DC voltage source and DC-AC converter. This solution causes high volume, weight, cost and poor efficiency. In this paper, a new topology for a three-phase boost inverter is proposed. The inverter is made of three boost converters...
A high intercept points, cost-effective, and power-efficient switching FET double balanced mixer (DBM) is reported. The Switching FET DBM demonstrated in this work offers input intercept points (IIP3) and conversion loss typically 44 dBm and 8.5 dB respectively with 15 dBm LO power for the frequency band (RF: 900-2150 MHz, LO: 850-1950 MHz, IF: 50-200 MHz). The measured interport isolation is typically...
A Triple Half Bridge (THB) Bidirectional DC-DC converter was proposed recently to combine different power energy storage elements/sources through a multi-winding transformer. The THB converter can be utilized in different applications including electric vehicle and distributed energy generation system. This paper presents the dynamic analysis and associated control design of this THB converter. An...
