Can this circuit step up to 100V? [Copy link]

Can this circuit boost the voltage to 100V? If I want to make a boost circuit, the adjustable PWM wave frequency can reach 30kHz, and the boost function from 5V to 100V is realized, and the current requirement is not high. Can it be realized?

[Can this circuit boost the voltage to 100V? ]

Considering that R14 uses such a large value of 10 kilo-ohms and L1 uses such a small value of 3.3uH, there is not much hope of rising to 100V.

There are many circuits that can generate high voltage, why must we use this circuit?

Why not search for a BOOST chip on the official website of the power management chip manufacturer? When the current is not large, it is estimated that there is an integrated MOS on the chip, which is reliable and convenient.

The inductance requirement is high, it can reach 100V, but the current will be very small, maybe a few milliamperes.

If you just want voltage without load, you can wind a lot of transformer coils, or you can use Tesla coils, Marx circuits, etc.

For a 20-fold voltage step-up rate, it is more appropriate to use a transformer (including autotransformer).

I have used this solution to make an instrument to measure voltage, and the load capacity is very poor.

The current is not large, I want to use it for boosting similar to mosquito repellent

It is more efficient to use a transformer. You can refer to the coal stove igniter circuit on the Internet.
