In this paper, a novel and simple controller for seven-level packed U-cell (PUC) grid-connected inverter is presented. The control method is derived based on sliding mode control theory. Making use of the measured grid voltage and computed reference grid current, the reference value of the inverter output voltage is determined. According to the calculated voltage value, the suitable control set is selected (offline) in order to satisfy the reaching conditions of two separate sliding lines. The sliding lines are defined based on the grid current and the auxiliary capacitor voltage errors. Simulation results are presented to show the effectiveness of the proposed simple controller in tracking the desired values.

A Control Method to Enhance Dynamic Performance of Parallel Inverters in Islanded Microgrid Kohansal, M.; Moghani, J. S.; Abdi, B.; Gharehpetian, G. B. (2011-09-10) A new method for the power sharing in parallel inverters is proposed in this paper. The power calculation unit of the conventional droop is improved to obtain fast transient response. The reduction of the circulating current between inverters during system dynamics is one of the advantages of this method. Also, the proposed control method has a good dynamic performance and power sharing. The simulation results are presented to prove the validity and the improvements achieved by the proposed controller.
An Optimized Analog Drive-Mode Controller for Vibratory MEMS Gyroscopes Eminoglu, Burak; Alper, Said Emre; Akın, Tayfun (2011-09-07) This paper presents an optimized analytical design procedure for the drive mode analog controllers used in vibratory MEMS gyroscopes. The behaviour of the controller during start-up is analyzed in detail including the effect of the limited voltage swing of the controller circuitry. As a result, an optimum design procedure is developed for controller design, which is also experimentally verified in a practical implementation demonstrating a settling time of only 50msec without any overshoot, for a gyroscope ...
A readout circuit for QWIP infrared detector arrays using current mirroring integration Tepegoz, M; Akın, Tayfun (2003-09-18) This paper reports a current mirroring integration (CMI) CMOS readout circuit for high-resolution Quantum Well Infrared Photodetectors (QWIPs). The circuit uses a feedback structure with current mirrors to provide stable bias voltage across the photodetectors, which can be adjusted between 0 V and 3.5V. The photodetector current is mirrored to an integration capacitor which can be placed outside of the unit pixel, reducing the pixel area and allowing to integrate the current on larger capacitances for large...
A Near State PWM Method With Reduced Switching Frequency And Reduced Common Mode Voltage For Three-Phase Voltage Source Inverters Un, Emre; Hava, Ahmet Masum (2007-05-05) The Near State PWM (NSPWM) method, which reduces the common mode voltage/current, is proposed for three-phase PWM inverter drives. The optimal voltage vectors and their sequences are determined. The voltage linearity and DC bus and AC output PWM current ripple characteristics are studied. The method is thoroughly investigated and its performance is compared to conventional methods. Theory, simulations, and experiments show that NSPWM exhibits superior common mode and satisfactory PWM ripple performance char...
A low-power robust humidity sensor in a standard CMOS process Okcan, Burak; Akın, Tayfun (2007-11-01) This paper presents a low-cost thermal-conductivity-based humidity sensor implemented using a 0.6-mu m CMOS process, where suspended p-n junction diodes are used as the humidity-sensitive elements. The measurement method uses the difference between the thermal conductivities of air and water vapor at high temperatures by comparing the output voltages of two hea ted and thermally isolated diodes; one of which is exposed to the environment and has a humidity-dependent thermal conductance, while the other is s...
