Abstract: In this paper, a novel passive filter installed at PWM inverter output terminals is proposed with an objective of eliminating the common-mode and differential-mode voltage generated by PWM inverter simultaneously For determining the parameters of filter, the filter transfer function is utilized to achieve a desirable filtering performance The detailed design procedure of the filter parameters is given The validity and effectiveness of proposed filter are supported by the simulation and experimental results carried out on 380 V/3 kW induction motor system Further investigations also demonstrate that the proposed filter permits motor to be connected with inverter through a long cable The side-effects induced by common-mode and differential-mode voltage such as shaft voltage, bearing current and leakage current are mitigated effectively

TL;DR: In this paper, a bandpass filter using only two resistors and two operational amplifiers is proposed, and the circuit has a Q equal to the ratio of the resistors.
Abstract: A bandpass filter using only two resistors and two operational amplifiers is suggested. The circuit has a Q equal to the ratio of the ressistors. While Q and gain are insensitive to temperature variations, the variations in center frequency is minimized uing a compensation scheme.

TL;DR: In this paper, an approach for the optimization of a hybrid combined power filter by using the GA method is presented, where the objective is to minimize the active filter (AF) rating.
Abstract: An approach for the optimization of a hybrid (combined) power filter by using the genetic algorithm (GA) method is presented. As the criterion for the optimization, the minimization of the active filter (AF) rating is adopted. The optimization studies are carried out for two characteristic situations of a DC rectifier load and a cycloconverter load. It is shown that a reduction of the active filter rating can be achieved if the load is a rectifier. However, a considerably higher active rating is required for a cycloconverter because of the presence of low frequency interharmonics and it is not possible to decrease it significantly by use of the passive filter optimization only. These examples clearly show why hybrid filter topologies and control techniques widely examined in the literature are suitable only for rectifier loads but not for loads with a broader spectrum. A possible modification of the AF filter control system which optimize the performance/rating ratio is proposed and discussed.
