Thank you FvM. I found some info on the configuration of LCL I'm interested in. The links are as below,

Hi! I'm programming a PIC16F690 to generate diagonal PWM outputs to be given to full bridge and later filtered. However the code is not working. May be some body rectify the issue. I'm getting some PWM output on P1A (RC5) pin only. The code is,
#include <xc.h>
#include <pic.h>
#include <stdio.h>...
Hi!
I'm designing a low power grid tie inverter. I'm little confused about the LCL filter configuration at output of Full-bridge to filter SPWM. It's a two stage inverter with first stage a flyback. The application note for LCL filter I'm using is at

I'm using the...
Does this implies that to make the design simple, if I'm using a 2 stage GTI where first stage boosts the voltage and 2nd stage uses a full-bridge configuration to produce sinusoidal waveform and if I use current limiting resistor (which will drive a feedback optocoupler) at the bottom mosfets...
I think you mean DAC and not ADC here?

So you mean that I take VCO output and let's say give that to some sort of ripple-carry binary divider like CD4040B. it will divide VCO output by 100 times. I will then AND operation of its output equivalent to 100 divider and then...
In context to damage of SMPS I have some bad experience of input rectifier and emi circuit malfunction. I'm still not clear why it happened as it happened many times even after this post https://www.edaboard.com/threads/235071/
I perceive that the fault was due to reaction of reactive circuitry...
Hi!
I'm designing a grid tie inverter. The important thing is it's synchronization with grid sinusoidal waveshape both in phase and frequency. I was planning to use PLL 4046B IC who will be given power from Vdd = 5 VDC. I'm not used to PLL so much so my thinking was that it will generate a...
Instead of controlling constant bulk current to initial maximum charge current written on label as 2.8 A for 7 AHr battery, I lowered the constant bulk current to 0.25 CA = 1.7 A as was shown for the tests in its datasheet graph by adjusting the resistor for bulk current and got the solution...
Dear FvM. Don't take it personally. My problem that I don't involve in politics and so being singled out from local colleagues and running electronic switching products design consultancy for last five years with zero finances.
Be a grown up man. I mean a battery having charge mechanism of applying constant voltage. Please read about the battery type as below link if you are innocent enough about not knowing it,

I have searched some...
Hi,
I made a SLA battery charger using my designed offline flyback SMPS and implemented charge algorithm using UC3909. Meanwhile I shopped a 7 Ahr battery from local market. Surprisingly when I read the label on battery, it was constant voltage type with cyclic use from 14.4 V to 14.7 V and...
Now I'm in better position to tell the right reason. At light loads the current sensing circuitry measures the low current demand and lowers the duty cycle. In real scenarios this duty is so small that almost diminishing. Thus in next cycle a high primary current flows through mosfet and current...
