  • Hi friends in this video I'm going to do something that nobody has done before, yeas you heard right, no body, i will convert a boost converter to a Buck-boost converter, that will keep the output stable no matter the input drops and rises like if you set output voltage 24V the input voltage can be 12V and 30V but the output will be exactly 12V , and one more improvement is you can no control the current from 0.01Amps to 20Amps maximum which is impossible before, now i made it possible by adding a coupled inductor, that acts like a Septic converter, but there is a disadvantage, the output voltage cannot be lower than 12V but can be adjusted from 12V To 60V and current up-to 20Amps , and minimum input voltage is 9V and maximum 30V
    [input Voltage]: 9V To 50V
    [output Voltage]: 12V To 60V (Buck Boost)
    [current Adjust before MOD]: (Not working only decreasing voltage) No Short circuit protection (Blows Fuse) and destroys the converter ,
    [Current Adjust after MOD]: Can be adjusted 0.01Amps To 20Amps Adjustable, Short circuit protection, now output can be shorted it will not blow the fuse :-)
    Before: The output had Spikes more than 70V and heatsink gives electric shocks,
    After: Output is stabe , don't give shock trough heatsink

      Its nice to build stuff that works by intuition and without a circuit diagram, but i did make a circuit diagram for what you built and i can tell you that it is not a buck-boost at all, but a flyback converter with isolation. The extra diode and its resistor is the snubber network to absorb the energy stored in the stray inductance of the primary coil and protect the mosfet.

    You did not test all conditions to confirm. Can we get 1.5V from 12V input?

    I tried it but it failed. As soon as the circuit tries to start switching current rises up to current limitation and the transistor heats up. No output voltage. I'm not sure whether the coil is wrapped correctly. I think the idea is to have a primary and a secondary coil with the same number of winding, right?
    It's hard so see on the video.

      You need a boost converter

    Finally I got it to run. It does exactly what you show but I'm still unhappy with the heat it produces. I hoped your modification will reduce switching losses.
    Maybe you like to advise another possible modification I use. By adding a few resistors I created a static MPPT solar battery charger with this boost converter. Therefore I used the two error comparators for input and output voltage (instead of output current). Setting the output limiter to the battery-full-voltage will provide a battery charger that stops when the battery voltage reaches the limit. The input voltage comparator will pull your input voltage down to the MPPT of your solar panel by increasing output current until the MPPT is reached. It runs fine with a 33V or 44V MPPT PV-Module charging a 16S LiFePO4 battery up to a limit of ~57V.

      Well-done 👍🏻
      If it produces heat , then i recommend increasing the winding turns!
      In my case it doesn't produce heat 🤔 see if it's overloaded?
      And i do not recommend increasing the voltage more than 45-50V !

    • @Electronic_For_You
      @Electronic_For_You  10 месяцев назад +2

      Before turning it on , be sure to use a Low power Input source like 12V and 1A only, in case someone is wrong it doesn't blow up ,
      Good Luck :-)

    • @Electronic_For_You

      I think it's because there are some resistive dividers for Voltage feedback and these converters are made for Boost mode so minimum input voltage should be 9V To Work well with the ic ,

      Здравствуйте, вы увеличили напряжение больше 50 В?
      А ваше устройство все еще повышает напряжение?
      Я думаю, если напряжение слишком сильно увеличится, потенциометр выйдет из строя!
