    How can one regulate the DC voltages from DC-DC inverter to the required voltages of the appliances using microcontroller? We are working on the implementation of DC-DC inverter that would power DC electronics effectively and accurately.

    An inverter needs Pulse-Width-Modulation and a voltage sensor for voltage regulation. Then when the sensor shows the output voltage dropping, the PWM circuit increases the pulse widths that raises the voltage. When the output voltage rises then the opposite occurs and the pulse widths become less.

    These are already very common and readily available. Does your system offer something that others don't?

    If you are (I'm guessing here as your post wasn't that clear on the issue) trying to make a system that automatically senses the required voltage and adjusts accordingly - you can't.....

    All my appliances use AC. My AC voltage is very reliable and is regulated very well by my electrical utility company. I wonder which appliances in Nigeria use DC and why do they use different voltages?

    Then later he says he wants an inverter to feed a regulated DC voltage to electronics?
    I use a wall wart to reduce the AC voltage then rectify and filter it to feed an IC voltage regulator since I do not need and have never used an inverter.

    - Can You tell me the exact DC voltage you want to give in input and required output?
    - Basic voltage regulators can help you best.
    But For some complex work :
    - You can use the Buck Converters using the nominal input of 24v -;100&p236typ=0.0003;100
    - In case of controlling high power lights or for any switching purpose you can also use the High-Current-N-Channel-PWM controller
    which requires a 12VDC Power Supply for proper operation. A separate power supply is recommended for external incandescent or high-power LED lights. This controller is capable of switching 100VDC at 5 Amps, and is able to switch considerably more current at lower voltages.

    You may learn about them and Implement useful prototype you want to.
    Hope This will help you out.
