A new circuit is proposed for single phase AC-AC conversion using Boost topology. Input Power factor, input current Total Harmonic Distortion (THD) and efficiency of the circuit are examined for the proposed circuit for different duty cycles. As the output is boosted pwm chopped in ac supply, the voltage gain of the converter has both Buck and Boost characteristics. A single bidirectional switch is used for power conversion and results show good performance. Analysis and simulation results for the circuit are obtained by using software simulation. The circuit can be used in low and medium power applications like light dimmer, speed control of fan motors and electric heater control etc. The main advantage of this new AC-AC converter is its superior power quality.

A Fully Integrated and Battery-Free Interface for Low-Voltage Electromagnetic Energy Harvesters
Ulusan, Hasan; Gharehbaghi, Kaveh; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2015-07-01)
This paper presents a fully integrated and battery-free 90 nm interface circuit for ac/dc conversion and step up of low-voltage ac signals generated by electromagnetic (EM) energy harvesters. The circuit is composed of two stages: The rectifier in the first stage utilizes an improved ac/dc doubler structure with active diodes internally powered by a passive ac/dc doubler and custom-designed comparators to minimize the voltage drops. With this, the efficiency is enhanced to 67% while providing 0.61 V to 40 m...
A Novel Multilevel Converter Used For Three Phase STATCOM under Unbalanced Load
Balikci, A.; AKPINAR, ERCAN (2011-09-10)
In this paper, multi-level cascaded Static Synchronous Compensator (STATCOM) is proposed using a novel converter having reduced number of switches. STATCOM is analyzed by using DSP and Matlab, interactively. The level shifted carrier based SPWM method, instantaneous single phase active (P) and reactive (Q) power algorithms are applied to control this converters. The performance of STATCOM is investigated for unbalanced reactive load conditions. The simulation results of Matlab alone and Matlab interactively...
A Parabolic Band Hysteresis Current Controller for Doubly Fed Induction Generators
Hamadi, Emad; Mortazavi, S. S. (2011-09-10)
A parabolic band hysteresis current controller (PBHCC) for DFIG is proposed in this paper to control the switching frequency variations in rotor side converter (RSC). A generalized online technique is used to determine the set of unique parabolic boundary for any operation speed. The PIHICC then utilized to regulate the current in RSC. In contrast to PI controller, PBHCC shows a very good transient behaviour. Beside that, the steady state performance is improved by reducing the switching frequency considera...
A Fully Integrated Power Management Circuit for Electromagnetic Energy Harvesting Applications
Gharehbaghi, Kaveh; Ulusan, Hasan; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2012-12-05)
In this paper a 90 nm power management circuit for vibration based electromagnetic energy harvesters is introduced to generate 1 V from the rectified DC voltage. A mode selector block is designed to detect the output DC voltage level of the rectifier and adjust the mode of the driver block. In order to set the output to the desired level, a regulation system with negative feedback topology is utilized. The circuit is able to operate with input voltages as low as 0.25 V. The simulation results also show that...
A Hybrid Antenna Element for Travelling Wave Dual-Plane Monopulse Slotted Waveguide Arrays
Gültepe, Gökhan; Doğan, Doğanay; Aydın Çivi, Hatice Özlem (2018-12-10)
A novel antenna element for low loss and low-profile dual-plane monopulse arrays is proposed. The travelling wave array has both sum and difference distributions in azimuth. The designed element is the unit cell of an interleaved slotted waveguide array feeding wideband printed antennas via probes inserted into waveguides from the slots. The use of printed antennas enhances the narrow sidelobe and efficiency bandwidth of the closely-spaced slotted waveguide arrays by up to 20%. The unit cells are modelled a...
