This paper presents the simulation of 3, 5, 7level inverters. The realization of these three different levels is done by cascading one, two, three H-bridges in series respectively in MATLAB. The use of simple control strategy which is applied for switching the switches at appropriate conducting angles with proper delays is presented in this paper. The reduction in harmonics is done with the hel...

The Designing of a single-inductor dual output (SIDO) fly-back power factor correction (PFC) converter is proposed, in which the multiplexing of a single-inductor is implemented with fly back converter through which each output can be regulated independently. The converter will be operating under in critical conduction mode (CRM).The efficiency along with power factor, total harmonic distortion...

This paper proposes an improved integration method to realize single phase power factor correction in continuous conduction mode by adding a ripple compensation network comprised of two resistors to the basic integration control circuitry. This method effectively reduces the total harmonic distortion (THD) in the input current. The proposed method is easy to implement. Theoretical analysis is g...

A new topology for translinear filters in CMOS IC technology is presented. This translinear filter is based on the exponential relation of passive PN-diodes in CMOS technology while the CMOS transistors only provide gain. From simulations, it is demonstrated that this topology leads to an improvement in high-frequency performance. Cut-off frequencies higher than 200 MHz with Total Harmonic Dist...

In this paper, we consider a designed and implemented phase-cutting dimmer. In fact, the dimmer is closed loop and a microcontroller calculates and then regulates the firing delay angles of each channel. Depending on the firing angle, the harmonic distortion in the input current will not comply with international standards, such as IEC 61000-3-2 (class C equipments). For solving this problem, e...

This paper presents a design improvisation of a flux pump-integrated 10 kW high-temperature superconducting (HTS) proof of concept generator for reduced harmonic distortion. To carry out the design improvisation, a finite element analysis (FEA) model of the 10 kW HTS generator is developed, and time-stepped magnetic transient simulations are conducted on the 2D model. The effects of stator yoke...

Abstract: Microsoft Windows® next-generation client operating system, more commonly referred to as Windows Vista®, is enhancing the quality and fidelity of the desktop and notebook PC audio experience. Manufacturers must meet strict audio performance requirements1 in order to license the Windows Vista logo for component hardware. These requirements are based on audio performance specifications,...

Using 1-μm InP HBT technology, a transimpedance amplifier (TIA) IC for optical links using 100-Gb/s dual polarization quadrature phase shift keying (100-G DP-QPSK) was designed and fabricated. Its wide dynamic range of 0.2∼2mAppd input current and good linearity of less than 3.3-% total harmonic distortion (THD) were confirmed. Also, externally controllable functions such as output amplitude ad...

The use of multilevel inverters is widespread in medium voltage applications due to their inherent voltage sharing among the devices.
