The input to the non-inverting terminal is voltage signal across a resistor. The resistor is connected between IGBT emitter and ground.
Thus the input is a voltage signal taken across that resistor. The frequency of the current is close to 25 kHZ.
The signal is applied to an opamp with gain...
The signal is coming form a resistor. The signal is actually the voltage across the resistor. This resistor is connected between the emitter of IGBT and ground. The IGBT is carrying current. Therefore the current also flows through this resistor.
The frequency of the current flowing through...
I have a question which is very serious. When I want to choose a low-pass filter, then what parameters of the signal determine what frequency it should have?
How should I decide the frequency I want ?
Hi, Thanks for ur reply.
I am going to feed this dc voltage to an single switch quasi resonant inverter, with inductance of 107 UH and capacitor of
0.3 UF.
This is basically an induction cooker circuit.
Do you have any idea how do I calculate the resistance of my load when a vessel is...
I have a supplied a full bridge diode rectifier with an ac 230 v 50 Hz.
I have not used any transformer.
At the output of the rectifier i have connected an LC filter.
The value of L is 380UH and capacitor is 5 U farads
Can any one explain me what voltage will i get across the c
L is...
Thanks a lot.
Can you also tell me how to calculate the resistance of a particular ic. Is it done by dividng that IC's Typical operating voltage by it's Typical operating current ?
Resistance= IC operating voltage/ Ic operating current ?
I want make a power supply to feed these IC's
LM35
Pic16f886
Ht12E Encoder
Rf Transmitter.
All the above Ic's require 5 Volts DC supply.
How do I make a power supply for These IC's. All are on the same PCB.
How do I calculate the Power required by a particular IC ?
Suppose an IC requires...
Can you please tell me the significance of the 100 K resistor connected across the bottom diode ?
And also the 200m resistor in series with Vac . Is it the internal resistance of the supply ?

Can you please tell me the significance of the 100 K resistor connected...
Okay. There is going to be a litz wire through which I am going to pass the alternating current. This will induce currents in the stockpot (Load).
It appears like a transformer with Litz wire having N turns and Stockpot having 1 Turn only with leakage inductance.
The Litz wire and Stockpot...
I have a Stock pot made up of stainless steel.
I want to use it as a load on an induction cooktop.
I waned to measure the inductance of the stockpot. It is cylindrical

Please advice

I want to use inverter on the load side because I am making an induction cooktop. and for cooktop I need a high Frequency AC Voltage.
Can you tell me how do I calculate the value of the capacitor which I will use between Rectifier and Inverter ?
