This is a buck converter - boost. Input voltage from 10V to 60V, output voltage from 3V to 60V. This is the basic circuit, It makes the voltage stable at the output. Although the input voltage has changed lower or higher. maximum current 15A Facebook group : bit.ly/CreativeElectronic Download file here : bit.ly/BUCKBOOST
The circuit works, but there is a serious error in the inductor-related schematic. The output of the L1 inductor coming from the +B input must go to the mosfet drain. And the output of inductor L1 coming from the ground must go to MBR20100. Pay attention to the polarity of C3. No litz wire needed, I used 17 wire in a computer source transformer core. Hope this helps.
I as him questions but he don’t reply in months so can u answer this question for me I build a buck booster converter but when I add any load the mosfet get fire 🔥 hot I use a power totem pole big transistor and the driver can drive 7 amp to the gate so it’s not the gate current and voltage the voltage is 12volt gate voltage from totem the mosfet or original 300 watt mosfet 110 amp rating and I use 2 so the that 600 watt but a 30 watt load get the mosfet fire hot the voltage booster up to 290 volt from a 700 amp battery and load at 60 volt 1 amp mosfet burning up but when I use push pull circuit diagram the mosfet is cold 🥶 at 500 watt
if the maximum input voltage is 60 Vdc, I think, the UC3843 must be feeding with a dc-dc converter (maybe voltage regulator - LM317), because the maximum Supply Voltage (Vcc) for UC3843 is 30 Vdc
hi, you have different values of the resistor on photo of the board (10R) and on the drawings of the circuit diagram (100R). I mean resistor which is placed on right side under the second mosfet (second from the left), please clarify what value is right? Beside please write which others pnp and npn transistors can also be used before the gates of mosfets?

For solar boosting, how to adjust the voltage when the sun ray does not reach up to maximum power to deliver up to 16 volt. Also the maximum ampere that it delivered.
Mppt is about delivering maximum possible power at any instand doesnot depend on irradiation. For voltage buck boost you can use buck boost module( cant remember the model name right now but buck one starts with LM and boost one with XL) for constant output voltage
@@koustavpramanick8373 The Efficiency point of a solar panel changes with iradiation: www.researchgate.net/figure/I-V-characteristic-with-shade-effect-of-one-Solara-PV-module-130W_fig3_268485690 So with clouds, a true MPPT reduces the load on the panel. If you live in a country where most day are clear and sunny, simply adjusting the MPP for that amount of sunlight, is better than a simple PWM charge controller, but it is not a true MPPT which constantly varies the load on the panel to figure out what delivers most power. Such a circuit needs a microcontroller that measure Voltage and current from the panel several times per second and varies the load as the guy did by hand turning the potentiometer in this video.

@@PhdHung for current to be high on the output side you have to operate the MPPT in the buck mode means you have to apply more voltage on the input side and you will get less voltage on the output side and I think you know the power remains constant in any DC-DC converter.
It is useful when you use wind power, when the wind is low. The voltage from the generator is small, it cannot charge the battery, the boost circuit will increase the voltage to charge the battery. of course with smaller currents.
