A highly compact continuous-time transimpedance low-pass filter (TILPF) topology is proposed that achieves a low input impedance and a 2nd-order transfer function in a single stage. This is suitable to perform current-to-voltage conversion with a built-in filtering characteristic in a passive mixer based wireless receiver. A 4th-order Butterworth prototype is designed with a cascade of the proposed...
A dual-rotor Hybrid Permanent Magnet Induction Machine (PMIM) having high torque and high power capability and possessing the advantages of both PM synchronous and induction machines can be a suitable option for electric vehicle application. This paper deals with the performance analysis of various possible topologies of PMIM and a conventional Squirrel Cage Induction Machine (SCIM) along with their...
This paper presents the magnetic field analysis of a dual-rotor type Hybrid Permanent Magnet Induction Machine (PMIM) using Finite Element Method (FEM) based software. Various possible topologies of the machine are discussed and analyzed using Ansys Maxwell software and then compared with a conventional Squirrel Cage Induction Machine (SCIM). The machine is in its preliminary stage of development...
A mathematical model of series-parallel compensation topology for contactless power transfer system is proposed in this paper. The effect of harmonics is considered to model the system parameter. A fourier series analysis is used in mathematical modeling. An experimental set-up of series-parallel compensated contactless power transfer system is built in the laboratory to verify the proposed model...
This paper discusses four compensation topologies of magnetic coupling system suitable for use in contactless power transfer (CPT) applications. The design and modeling process of CPT system is described in detail. Resonance between the source and load is achieved with compensation capacitors connected at the terminals of the coils. Electric equivalent circuit models are used to describe each circuit...
In drive system of an Electric Vehicle (EV) power train, the battery and power converters are most important parts. In this paper a noval drive system is proposed for Electric Vehicle(EV) power train. Here we used a real time electric circuit based battery model as a power source of drive system unlike conventional ideal battery source. To convert fixed DC to three phase AC, a new topology of DC to...
Due to large leakage inductance, compensation is usually necessary in contactless system to achieve the required power transfer. A contactless power transfer system is designed with two such compensation topologies and are presented in this paper. Primary compensation is designed to make the primary phase angle equal to the secondary resonant frequency with minimum VA rating of the power supply. Secondary...
Balancing the communication traffic between multiple lightpaths, using particular RWA protocol for all class-of-traffics, or a combination of both leads to the degradation of the WDM network performance. Hence for better performance of WDM network, in this paper we designed and analyzed an advanced centralized priority based RWA protocol (ACPR) for WDM networks in which appropriate RWA methodologies...
Dynamic Voltage Restorers are utilized to protect sensitive loads from voltage disturbances which take place in the distribution systems. The three-phase four-leg topology of DVR is more advantageous over the other topologies. But it requires higher switching operations of the VSI for tracking the reference voltages through hysteresis. This paper presents two switching minimization control algorithms...
