#LOW PASS PI FILTER DESIGN SERIES#

Pi filter is an electronic filter circuit consisting of a series connection of a capacitor and an inductor, followed by another capacitor, arranged in the shape of the Greek letter “Pi” (π).Sensors & Actuators Certification Course.Analog & Digital Electronics Certification.Fundamentals of Multibody Dynamics (MBD).Certified EV Technician Training Program (CEVT).Nanodegree in CAE (Consumer Electronics).PG Diploma in Hybrid Electric Vehicle (Upcoming).Electric Vehicle Nanodegree 100% Placement.

because i had ask u in other posted but u didnt reply me hehe~~~~anyway thank for u willing to help about this.and sorry for my poor english and no good technique for making inductor.if i make high frequency for the spwm.then maybe i will reduce my 10 Henry inductor value.that would be cut cost for my design. really no convenience to puchase and keep changing component value. , issit this concept for choosing component really available to use it in real life ?.to generate. can i use concept to choosing component value ?.F_(cutoff frequency)=1/(2π √LC). but for my simulate cannot be handle so fast mirco pulse always due to error.erm if i use 2KHz. then i desired this such big inductanceīut just wanted to ask, if i control my pulse of spwm to generate high frequency at 2KHz.actually wanna try on 5Khz. cannot generate pretty good sine wave.and use 1000nF to substitution. if i choose 1000uF or other value.will be come out problem for the sine wave.

Why i choose 1000nF.because tested in software really due to many condition. just know a little concept of the LC circuit to choose Cut off frequency.F_(cutoff frequency)=1/(2π √LC). i had test many type of value in my design L=9.8 also can get sine wave between 8.8H to 9.8H only available to getting sine wave.very weird i dont know what problem for these value happen.So just really need ur guide for understanding to choosing the value of L and C to oscillate Sine wave.

to the spwm pulse the full cycle period is 50HZ and i use the virtual transformer to step up the voltage and in the last step i setting my component value L=8.8H the Capacitor I used C=1000nF. i really not understand for choosing the L and C value.for my proteus i had done it is using some knowledge for transistor, with guessing and luck to success it.i used the H-Bridge configuration depend on the BJT. for my sine wave inverter design i had success done it proteusīut one problem. Gold smith need ur guide for the LC Circuit calculation. The lowest frequency that you have in the spectrum of your SPWM is 50HZ, so the cut off frequency, can be higher than this, when your carrier frequency is high ! thus the value of elements of your filter will be reasonable, and it will be cheap ! Īs you perhaps, know, each SPWM consists a low frequency component and a high frequency component ( with many side bands ). I selected 4 kHZ because, you need 50 HZ at your out put !!! did you confused about this ? as you probably know, if you try to achieve a sine wave from a 50HZ square wave, it will be very hard and expensive. ( i think your assumption isn't correct ). ĭo you know meaning behind order of each filter ? if no, i can describe all of them for you. You wrote one pole, nearby some of your filters.

A question about the diagram that you made : do you know meaning behind pole ? if yes, do you know that the number of poles of each circuit is depends on what ?
