How to make a boost converter?

Hi all. Today I'll show you how to make a DC-DC boost converter with your own hands! The circuit is very simple, it is based on a symmetrical multivibrator familiar to all radio amateurs. The converter can increase the voltage of 12 volts to 24, and the power of the converter is about 48 watts.

Nicely explained video, you are going in the right way. About the circuit, the negative feedback can be improved, the way it's done it's not the best for turn off the mosfets, it should be some type of shmitt trigger, or the gain should be increased by adding another transistor, to make the gate control more sharp

Thank you. Yes, I think you are absolutely right.

Heavy Duty MOSFET Modules could be used if you use a heavy duty heatsink.

[@bazrazin1]

can you get split rail supply like +15v,-15V & 0V from this to be used for audio opamps if one of the o/p diode & capacitor polarity is changed.

no

What is the frequency.?

[@michaelbenard6758]

What frequency and duty cycle did you use

[@Den_Electro_channel]

The multivibrator operates at a frequency of approximately 15 kHz.Duty cycle 50%
