Dear BPB Yes, i have seen, infact gone thru this BPB book recently,Checked out all the Schematics but did not Purchase this particular title because there was nothing New in this one, all the Schematics were already Present in GT Publications, its first Edition (Vol 2) came out in 2000 & first Vol in 1998

Dear Forum iam not crossing my sword with Sasi, these Pics have been Posted from the Book "Advance Inverter & Ups Circuits-vol2" the Publisher & Author is Mr. G.T Gupta. Its Very Painful when somebody claims the ownership of your work, we all refer to some books or Manual, it would be great if we just mentioned "this is from XYZ book" authored by Mr.Xyz. Atleast we know that we have done the right thing and can have peaceful sleep at night. Sasi's Cutoff Circuits are his Own Piece of work which i appreciate Audioguru, i couldn't find the ISBN number, iam not too sure if i can Scan the Entire Manual and Post it here in the Forum, i maybe prosecuted, if i don't obtain Permission of the Publisher. the Cost of the Book is Rs.70 ($ 1.60) if anybody is interested in buying the Manual, i surely will help arun

Here's APC UPS Schematic with Trouble Shooting Tips !

Here's the Circuit We all are Discussing ! :)

Dear audio Guru As I said before there are Over 25 schematics in the Manual, the circuit which you(we all) are talking about is in other page, i took Snap of another circuit. its sad that i have not perfected the art of Photography

I'd Like to add The Above Said Manual is Published by M/s. G.T. Publishing Company, Jaipur, India. The Author/Editor is Mr.G.T.Gupta, Director, GT College Of Engineering & Hardware,

Phase Controlled Charger Circuit Features: Constant Current & Constant Voltage charging,Precise Cutoffs & Trickle Chraging We Sell this circuit as a Seperate charger for People Who want Battery Chargers/self Start Generators As For Sasi's over heating of 0-180 Coil we use a 10 Ohm, 40 Watt Resistor in series with the 180 Tapping. People who have used this charger said that it was Better than an SMPS Charger . People in country like ours (Rural Population)cannot afford a very expensive inverter which needs high Bill Of Material (Inverter trafo + Charger Trafo + Mosfets+3055 transistors+Relays etc). ??? the inverters based on this kind of charging are alive since 6 years to tell their success story. ;D i have to take these Pics because the Publisher and the Editors have Painstakingly decoded the Inverter & UPS PCBs available in the market for training the Students & hobbyists . They deserve their own credits. :D arun ;)

PCB Pattern, 500 Watt Inverter !

Here's "Sasi's" PWM Circuit !

Hello Forum! Good to Find some straight answers, its time for a

Hello Forum! :D My comment on Mr. Sasi's circuit

Hello Forum! :) I have been in the inverter & UPS Field for Quite Some time, I have a manufacturing unit For Inverters & UPS, M/s. Sunlite Technologies, HYD, India. I'd Like to Comment on Mr. SASIDHARAN's
