ups circuits

hi to all
i have a problem i want very simple UPS circuits without any microcontrol please help me but only without any microcontrol
thanks

simple ups circuit

if you want a very simple inverter https://www.electronics-lab.com/projects/power/033/index.html but you must change the final tranzistors with some power mosfets.
If the supply is used for computer and monitor only, you can build a smps with CC output (300V).

In both situations you must make a switch device with relays and a battery charging circuit.
Goodlock.
 

inverter circuit 1000w

The 500W inverter at Electronics-Lab was recently changed by the moderator:
1) It doesn't have enough output transistors.
2) Its oscillator has a 4.7uF non-polar capacitor.
3) Its oscillator has a 1k resistor but Texas Instruments says not less than 10k. It should have a 0.1uF metalized plastic film non-polar capacitor and a 39k resistoir for 60Hz and a 47k resistor for 50Hz.
4) There are no spike protection diodes.
5) It uses two LM324 quad opamps instead of a single LM358 dual opamp.
It is a mess. The moderator deleted my fixed version that works fine for years.

Electronics-Lab also has another inverter that doesn't work. It blows up its capacitors that have backwards polarity, its transistors have avalanche breakdown and have a base current much too low.
The moderator says it works fine.

simple ups

Why do you show a 28.6W 13V power supply?

A 1500W inverter will draw a current of 150A from a 12V battery which will cause it to boil or explode.
150A circuits are not simple.
 

ups 1000w

I am agreed with AUDIOGURU's reply.

That 500W design is totally a mess. The selection of RC for 50Hz is totally wrong.

Please post any better design of UPS

I never found a "simple" UPS as of the moment...and with that load requirements? i'll buy a generator if i were you..

Great circuit ssajidhb, will give it a try.

design with simple ups

Not easy
 

circut of ups

I am reading & watching EDA Board from some time I think no one is serious. Helpers did not post practical projects to bulid they think every one is as experienced and qulified as them.
Please explain your circuits & projects properly.
Thanks for reading.

The circuit you provided is not matched with P.C.B & Layout.

Where is the Circut of the P.C.B you Provided?

The Program is for the circuit which use PIC16F84.

DO NOT CONFUSE THINGS

please dont post files only to get points.
the firmware is for 16f84 and the pcb is using 16F72
the file named ups.pdf is from microchip site with file name renamed

dear ssajidhb,
I dont have any points, and I need the circuit now, please email the circuit and other details on zimsonmbm (at) yahoo (dot) com,
I will be obliged
