Optimal Single Resistor Damping of Input Filters
نویسنده
چکیده
A general procedure is outlined for optimizing the damping of an input filter using a single resistor. This procedure is employed to derive the equations governing optimal damping of several basic filter circuits. Design tradeoffs are discussed. Additional criteria are derived that allow employment of these results in design of multiple-section cascaded filters with damping.

Design, Application and Comparison of Passive Filters for Three-Phase Grid-Connected Renewable Energy Systems
Second and third-order passive filters (LC and LCL) are interesting filters to use for grid-connected PWM inverters. Because of the stability problems of these filters around resonance frequency, series and damping resistor can be add to an LCL filter. However, the resistor value has impact on the filter respond, voltage and current harmonic distortion and filter power loss. In this paper, the ...

Harmonic resonances may damage equipments and interrupt electric power customers services. Shutdowns may affect seriously harmonic resonant frequencies and may initiate new resonances in distribution power systems. This paper proposes various techniques for damping harmonic resonances in power systems[1-4]. A series reactor should be connected in series with the shunt power factor correction ca...
متن کاملUniversal Current-Mode Biquad Filter Using Single Inverting Second-Generation Current Conveyor
A new three-input and single-output current-mode biquad filter using one plus-type inverting second-generation current conveyors (ICCIIs), two grounded capacitors and two resistors is presented. This filter can simultaneously realize five generic low-pass, band-pass, high-pass, band-reject and all-pass filtering signals. H-Spice simulations with 0.35μm process are used to validate filter feasib...

This paper presents two novel electronically tunable universal filter configurations employing a single new active device, namely the current follower transconductance amplifier (CFTA). The first proposed current-mode universal filter with single input and three outputs consists of one CFTA, one virtually grounded resistor and two grounded capacitors. It can simultaneously realize low-pass, ban...
متن کاملMF8 4th-Order Switched Capacitor Bandpass Filter
The MF8 consists of two second-order bandpass filter stages and an inverting operational amplifier. The two filter stages are identical and may be used as two tracking second-order bandpass filters, or cascaded to form a single fourth-order bandpass filter. The center frequency is controlled by an external clock for optimal accuracy, and may be set anywhere between 0.1 Hz and 20 kHz. The ratio ...
