Push Pull Pure Sine UPS/ Inverter Combo

Technology of Sine wave Inverter For Sale In Bangladesh OR Abroat


C Tech Inc has developed a new micro-controller based digital sine wave Home UPS using low Impedance dead band push-pull topology. This inverter is best suited for manufacturing for domestic applications as it is simple and easy. It consists only few components which are easily available, does not have any smd
components and with a single sided PCB..

Functioning LCD which will display all the parameters of the system and indicates any error during the functioning of the inverter. A low cost 16 character single line LCD will be of scrolling type, Showing the status of the inverter such as battery voltage, mains voltage, inverter output voltage, inverter standby on/off, charger on/off, and many more. It is very simple to handle and very easy to set the
values in the menu driven set-up mode. This inverter is a very robust design, which will not fail, in any extreme conditions. LCD display for indicating various status of the system like inverter voltage, mains voltage, battery voltage, % of load, overload/short circuit status, battery low status, charger status etc.
LCD based Menu driven setup of various parameters like battery full charge voltage, battery low voltage, load condition, Inverter output voltage, charging current etc.

Protections against: Overload, short circuit, battery deep discharge, battery over charge, mains over voltage, reverse connection of phase in & phase out, reverse connection of phase and neutral of mains input. In all these error conditions will be shown in the LCD display. Delayed inverter cutoff for conditions like battery low, overload, short circuit etc. The system will automatically restart from cutoff after a few second buzzer beeps. The system will go to permanent cutoff if the error condition exists even after 4 restart.
Bill of materials: Attached file.
1. LCD will display
!"Battery voltage
!"Inverter output voltage
!"Percentage of load
!"Mains voltage
!"Charger on/off
!"Inverter standby on/off
!"UPS mode / inverter mode
!"Phase input output reverse
1. If 440V is applied to the AC input, it will not fail. It will indicate high voltage cut-off and
restart when voltage is normal.
2. If AC mains is given to the inverter output, it will not fail. It will indicate phase input output
reverse and continue to work after it is rectified.
3. It has fold-back current limiting for short circuit and heavy loads. At short circuit or heavy
loads, current limiting action will take place instead of tripping which will lead to more reliability.

Ver 2.01
!"Overload : if load is above 100% and below 300%
!"Heavy : if load is above 300%
!"Short circuit
!"Overload trip
!"Heavy load trip
!"Short circuit trip.
2. Menu driven set-up.
There is no preset, the parameters such as battery low, charging current,
inverter output voltage, load etc can be set by scrolling up and down keys and press enter.
3. Inbuilt SMPS type constant current charging with full charge cut-off.
4. 20KHz operating frequency while charging, absolutely no sound.
5. Pure sine wave output
6. Micro-controller based very low component cost design
7. Single sided pcb, easy to assemble without any smd components
8. Ideal for Mixed load application

Pure sine wave inverter output. battery voltages in the range of 12V, the voltage drop in bridge topology
will be more resulting in less efficiency and more heat. But in conventional push-pull method even though
the conduction loss is low,
