How to generate a Modified sin wave...?

[4pyros]

where is the 150 v taping line from the triac on top of the header going?

 

[koolguy]

To transformer winding...

 

[4pyros]

OK can you show us the transformer wirring?

 

[koolguy]

here it is........

 

[4pyros]

I am gessing some kind of voltage regulatoin.
Where did you get that circuit?

 

[koolguy]

Don't gess i think it is for battery charging when the inverter is in off state....the other transformer is for regulation....

 

[koolguy]

Can anyone explain me the working of it??

Where did you get that circuit?

from manufacture

from manufacture

I Can't imagine any Manufacture supplying a Poor Quality, HAND DRAWN Circuit like that.
And without knowing the Programming for the "PIC", It isn't a Practical circuit to Determine what it is ment to do or to Duplicate it .

The schematic is redrawn by me only some part not fully sketched....

hi

i found this circuit while searching on Google what is the use of diode and Resistance // to it??

 

[alec_t]

In standby the battery is charged via R1. When the battery is supplying current the diode by-passes R1.

The circuit i posted back, as i said i think it is used for dc battery charging but there is no diode rectifiers at center tap so how it is working??
