This paper discusses about Hartley oscillator circuit, it’s working, advantages and disadvantages, applications The Oscillator design uses two inductive coils in series with a parallel capacitor to form its resonance tank circuit producing sinusoidal oscillations.

A new CMOS fully differential bandpass amplifier (BPA) based on the structure of a transresistance (Rm) amplifier and capacitor is proposed and analysed. In this design, the Rm amplifier is realised by a simple inverter with tunable shunt-shunt feedback MOS resistor and tunable negative resistance realised by crosscoupled MOS transistors in parallel with a current source. The capacitor is in se...

This paper compares four converter topologies for the implementation of flexible ac transmission system (FACTS) controllers: three multilevel topologies (multipoint clamped (MPC), chain, and nested cell) and the well-established multipulse topology. In keeping with the need to implement very-high-power inverters, switching frequency is restricted to line frequency. The study addresses device co...

Loss minimization in power system is an important research issue. Transmission line losses in a power system can be minimized by means of reactive power compensation. The continuous demand in electric power system network has caused it to be heavily loaded leading to voltage instability. This phenomenon has also led to voltage profile depreciation below the acceptable secure limit. The signific...

This paper presents a method of enhancing the performance of a four-phase switched reluctance motor by using capacitors to produce additional supply voltage during the rise and fall periods of a motor phase current. The voltage rating of the inverter components increases and extra capacitor/diode combinations are needed. The operation and analysis of a series voltage boost circuit are detailed ...

A boost converter which employs a flying-capacitor passive lossless snubber to reduce the losses caused by the reverse-recovery characteristic of the boost rectifier is described. The passive snubber consists of a snubber inductor, two snubber rectifiers, and a snubber capacitor. The losses are reduced by inserting a snubber inductor in the series path of the boost switch and the rectifier to c...

The power of energy storage devices is characterized by capacitance and the internal resistance. measured on an assumption that charges are stored at electrode interface electric double layer behaves like ideal capacitor. However, in most cases, not so a constant phase element (CPE) used instead capacitor to describe practical observations. Nevertheless, another problem with use CPE does give d...

The design of modified Wilkinson power divider is done by dividing Quarter wavelength transmission line into two, in-between that complex isolation component and compensation capacitor is added. Complex isolation component provides physical separation and electrical isolation between two output ports. It consist of parallel or series RLC circuit is chosen to realize. To get the widest bandwidth...
