The required output from the inverter is 220/230V at 60Hz, with an output power of 1000VA. The first circuit represents a basic commercial UPS design, providing a constant regulated 5V output and an unregulated 12V supply. Upon failure of the electrical supply, the battery takes over without causing voltage spikes on the regulated supply. This circuit can be adapted for various regulated and unregulated voltages by utilizing different regulators and batteries. For instance, to achieve a 15V regulated supply, two 12V batteries can be connected in series with a 7815 regulator. The circuit offers significant flexibility. Transformer TR1 has a primary winding suited for the local electrical supply of 240V in Nigeria, while the secondary winding should be rated for at least 12V at 2A, though a higher rating of 15V is permissible. The fuse FS1 is a slow-blow type that protects against output short circuits or faulty cells in rechargeable batteries. LED1 illuminates only when power is supplied; during a power failure, the LED turns off, but the battery maintains output voltage. The second circuit simulates operation with mains power applied. The design includes a zener diode circuit at the transformer output to limit or regulate the load current.
The specifications for the UPS include 1000VA output, powered by a 12V, 100AH lead-acid battery, along with battery charging circuitry featuring low battery and overcharging cut-off circuits, alarm circuits, a changeover module, voltage level bar display, surge and sag protection, overload protection, and MOSFET power control. The designer has been busy redesigning the circuit diagram using EAGLE software and Ktechlab, culminating in a large diagram organized into seven modules. The circuit operates impressively well, with plans to commercialize the design.
Inverters are recommended as secondary power supplies capable of powering devices such as PCs, lights, TVs, and other appliances drawing approximately 1000VA, including air conditioners, irons, boilers, and freezers. These devices require significant current, necessitating a battery bank to sustain operation for at least one hour. For higher power outputs, such as 5000VA or more, multiple inverters can be synchronized to achieve the desired performance, although the cost increases with power output.
The described inverter circuit is versatile, allowing for various configurations and adaptations based on user requirements. It supports a range of applications from simple household power backup to more complex systems, making it suitable for both personal and commercial use. The design emphasizes reliability and safety, ensuring that critical loads are maintained during power interruptions while providing protection against potential faults.The required output at the inverter is 220/230V @60Hz. Basically, let me say i need an inverted circuit diagram with an output power of 1000VA. While the first circuit is a simple form of the commercial UPS, the circuit provides a constant regulated 5 Volt output and an unregulated 12 Volt supply. In the event of electrical supply line failure the battery takes over, with no spikes on the regulated supply.
That first circuit can be adapted for other regulated and unregulated voltages by using different regulators and batteries. For a 15 Volt regulated supply use two 12 Volt batteries in series and a 7815 regulator. There is a lot of flexibility in the circuit. TR1 has a primary matched to the local electrical supply which is 240 Volts in Nigeria. The secondary winding should be rated at least 12 Volts at 2 amp, but can be higher, for example 15 Volts.
FS1 is a slow blow type and protects against short circuits on the output, or indeed a faulty cell in a rechargeable battery. LED 1 will light ONLY when the electricity supply is present, with a power failure the LED will go out and output voltage is maintained by the battery.
The second circuit simulates a working circuit with mains power applied. Actually i can design a UPS circuit on my own, which will take me a while and i don`t have that time now. that`s why i just want a ready-made one from anyone. so i need an inverter circuit that can power such a transformer. Again i want to believe that a zener diode circuit must exit at the transformer output to limit/regulate the amount of current drawn by the load.
WOW! I`ve really succeed in building my own 1000VA ups from scratch. Being a student of Elect/Elect i resulted in learning the basics of inverter and bang! successfully designed and constructed my own fully functional UPS. Thanks to the book: Art of Electronic. The student manual was pretty very helpful. The UPS spec are: 1000VA, 12V, 100AH lead-acid battery powered, battery charging ciruitry with low battery/over charging cut-off ckt, alarm ckt, change over module, voltage level bar display, surge and sag protection, overload protection and MOSFET powered. i owe appologies to the mail senders of whom i`ve not been able to reply. i`ve been busy of late, and moreover i`m ve been redesigning the circuit diagram with EAGLE software and ktechlab.
the diagram is large and in seven modules. i`ve succeeded in putting them together as whole circuit(Thanks to EAGLE). Again, i`ve to do lots of explanation of how everything works and that`s part of the delay. The circuit works impressively fine! And i`m planing on going commercial with it. First, i want to setup my own domain and post everything their. For the mean time, i would advice intrested nairaland to learn how to use EAGLE software on Linux. It amazing. L8a. logging in for the first time i was suprised to see that there are people in need of my field of specialty, i have been desinging power inverter ( or converter as some people might call it) since 2001, i must say that as of now i have improved greatly in the field and through hard work and research i can now design inverter that can boost an output power of 1000VA or more depending on the clients requirements. in the case of higher power output, of about 5000VA or more, one can have multiple power inverters and synchronize the power to get more juice out of it.
however the higher the power the more expensive it becomes to get one, i would recommend the use of power inverters as a secondary power supply, that could carry your pc, lights, tv etc any power load of about 1000VA for example AC, pressing iron, boiler, freezer etc these draw a lot of current of current and that means you would require a bank of battery array in other to make it last for a least "1 hour", which is quiet ridiculous. but if you maintain a low power out-take and with a 24 volts 200AH b 🔗 External reference
