A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...

although many mathematics-based and heuristic approaches have been recently developed on optimally allocation of tcscs for lines overloads reduction and buses voltage stability enhancement during fault conditions, the works on the tcscs efficiency to achieve the abovementioned goals are rare. this idea that tcscs can surely enhance the system’s security must be comprehensively investigated. in ...

The conventional SVPWM algorithm gives good performance for control of induction motor drive, but it produces more acoustical noise resulting in increased total harmonics distortion. The random pulse width modulation (RPWM) techniques has become an established means for mitigation of undesirable side effects in PWM converters, the use of voltage source inverters in adjustable speed ac drives in...

Variable speed drives (VSDs) use power electronic components as controlled switches which distort the sinusoidal current and voltage waveforms of AC grid due to harmonic injection at the point of common coupling (PCC). These harmonics and distortions are propagated through the power network and affect all other connected loads. So, the shunt active power filter (SAPF) is one of the proposed too...

In modern electrical distribution systems harmonic distortions are created from a number of sources such as variable frequency drives, lighting, computers and nonlinear loads. Such harmonic distortions produce a variety of undesirable side effects ranging from poor power factor, motor failure to overloading of transformers and conductors. Now a days increasing number of renewable energy systems...
