In this paper control of Goertzel Algorithm based shunt active power filter with sliding mode controller is considered. Shunt active power filter involves harmonics mitigation due to three phase non linear loads under balanced and unbalanced load conditions. The sliding mode controller is used to regulate voltage of the capacitor used in inverter. The sliding mode controller improves the dynami...

IIn this paper, a tunable single-amplifier biquadratic lowpass filter is presented. It consists of one balanced low-gain current amplifier and a second-order MOSFET-C feedback network. The filter was integrated in a double-poly 0.6 pm CMOS process and operates from a 3.3 V power supply. The pole frequency is tunable from 15.2 to 17.2 MHz, the pole Q is 3, the spurious-free dynamic range is at l...

A novel analogue power-efficient 2-D programmable finite impulse response image filter is proposed. This solution is based on the current-mode Gilbert-vector-multiplier operating in the weak inversion region, which allows for ultra low power operation. The main advantage is in the asynchronous and parallel calculation of all pixel values without using any clock generator. The filter is a progra...

We report on the spurious suppression effect in lowmicrowave power transmitters by high temperature superconducting (HTS) bandpass filters (BPFs) which are promising for devices requiring BPFs with high-frequency selectivity. Some of the major issues on the power BPFs with HTS planar circuits for wireless communication applications are reviewed. As a case study for the HTS filter and its spurio...

This letter investigates the relationship between antenna position and data communication performance in a magnetic resonance wireless power transfer (MRWPT) system. In MRWPT information such as the types of equipments, the required amount of electrical power, or the timing of power transfer should be exchanged. It is assumed here that power transfer coils in the MRWPT system are employed as an...

This paper presents a hybrid active power filter for a three phase four wire distribution system. The scheme consists of a zigzag transformer, single phase active power filter connected in series with the utility neutral and a coupling capacitor connected in series with a voltage source converter of the active power filter (APF). The addition of coupling capacitor permits the reduction in DC li...

Power control is important in maintaining the communication link quality under fading and interference situations. In recent years, research on power control has been conducted toward reducing power consumption while maintaining reliable link quality. These previous works, however, did not try to optimize power control algorithms under practical constraints. In this paper, we first observe and ...
