    Help regarding thyristor triggering

    I need to control the ac power using two back to back thyristors. I've developed the code for the gate pulses and i need to design the triggerig circuit. Could anyone direct me to some useful websites that deals with practical triggering circuit? I've referred some text books but I am not...

    simulation circuit in proteus to convert current into voltage

    yes. my project is to measure power. I'm getting the output for linear loads(i used voltage source for both current and voltage). Now I need to check with nonlinear loads so that my code is correct. Any idea to implement phase lag or lead in proteus would be helpful.

    simple phase delay circuit to use in proteus simulation

    I'm currently working on power meter project using atmega microcontroller. In order to simulate it in proteus, i need a phase delayed circuit inorder to model inductive loads. In the component, there is a block called time delay but the value is zero till the delay time is reached. An idea on...

    Power measurement using atmega microcontroller

    I need to measure power using microcontroller for my project. I'm using atmega 88. Right now, I've stepped down the input supply(voltage and current) and DC biased it so that the value doesnot go to the negative. What I've decided is to sample both voltage and current simultaneously(changing...

    Doubt in multiple ADC conversion

    Doubt regarding multiple ADC conversion My objective is to convert voltage and current simultaneously in an atmega controller and to find the power by multiplying it. I've written the following code for ADC conversion: interrupt [ADC_INT] void adc_isr(void) { data= ADCW; if(adc_channel==0) {...

    Related to transformer Equivalent circuit

    While modelling a transformer we must account for the lossses and leakage flux in the equivalent circuit. Core losses are modelled by Resistor. But how come inductors are used to model the leakage flux?

    Simultaneous ADC Conversion using atmega88.

    My signal frequency is 50Hz. I'm planning to use a sampling frequency of 200KHz for an energy meter application. Will it cause any accuracy problem?

    Simultaneous ADC Conversion using atmega88.

    My project is to measure power using atmega microcontroller. I've studied the code for ADC conversion of voltage and current. Is it possible to simultaneously convert both voltage and current? I'm new to AVR coding.

    [ask]How to convert 1 phase to 3 phase?

    I'm not sure if this technique exists but its my idea. First rectify 1 ph supply into dc. Then use an 3ph inverter to get 3ph ac.
