The work delineated in this paper deals with the reduced sensor-based operation of PV-DSTATCOM (Photovoltaic distribution static compensator) focusing on voltage source inverter (VSI) switch current limiting control. In study, soft computing technique control based variable leaky least mean square (VLLMS) algorithm is modified to incorporate both sensor and schemes. DSTATCOM predominantly intro...

In recent years, electric propulsion systems have become widely, used and these strict limits in volume weight. Therefore, it is necessary to reduce the weight of inverter-motor drive system. a typical system, at least phase current sensors are required. order number sensors, this paper proposes method for measuring using DC link Two currents per system measured during one period switching freq...

This paper presents the overall review of torque ripple reduction techniques in brushless DC motors (BLDC) and different multilevel inverter topologies suitable for BLDC motor drives. BLDC motors are widely used for household applications due to its features of high reliability, simple frame, high efficiency, fast dynamic response, compact size and low maintenance, etc.. The switches are electr...

The Class DE inverter offers high-efficiency power conversion under high operating frequency (megahertz order) with low switching noises and low switch voltage stress. It has been applied to dc/dc converters as high-density power sources. Conventional converters with the Class DE inverter are controlled by varying the operating frequency, the switch duty ratio or the phase difference with two i...

A robust relaxation-oscillator-based conditioning circuit for remotely located resistive sensors is proposed in this article. The uses a simple analog architecture comprising an integrator, Schmitt trigger, inverter, and novel switching logic as its core blocks. provides linear digital indication of the sensor resistance. output independent many non-idealities such bias-current offset voltage O...

This paper proposes five level diode clamped Z source Inverter. The existing PWM techniques used for ZSI are restricted for two level. The two level Z Source Inverter have high harmonic distortions which effects the performance of the grid connected PV system. To improve the performance of the system the number of voltage levels in the output waveform need to be increased. This paper presents c...
