Hi!
I am thinking of designing an inverter to produce 230V,500W.The battery voltage i can use is 12V.I must be able to provide the required output for 5hrs continuously.The battery size and cost should be minimum and the battery used should be a lead-acid battery.
The following are my doubts regarding the design.
1)What should be the ampere-hour rating of the battery i should use to provide the current required for the given power and how to calculate it?
Is it possible to use 12v 4.5AH or 12V 12AH(bike battery) or an computer UPS battery,if so how long will these provide the required power.
2)PWM or square wave inverter,trapezoidal wave inverter,sine wave wave inverter.What is the advantage of using one over the other?
3)Can the household appliances work safely with a PWM or trapezoidal wave outputs?
Also please suggest me a good book or a site for efficient design of inverters.
Thanks in advance!!
