is there any chip that take logic input and generate 15V-20V output?

I've been working on a Single Phase IGBT Inverter with PWM and Zero Crossing Detector for months. Turns out I forgot to build the gate driver (i know it's stupid but I'm also working and studying at the same time so it's kinda hard to catch up) However,

my zero crossing detector is used as PWM from Arduino. (i only use digitalread and digitalwrite code with pin 3 as input and pin 9 as output)

At first, I connect pin 9 straight to the high side IGBT gate and inverted pin 9 to the low side IGBT gate. It was a mistake because the gate needs 15V to be turned on and the IGBT overheated because of shoot through.

Now I need a chip that takes logic 2,75 V input and amplifies the voltage without interfering the frequency. Is there any?

Here's the schematic to the circuit.

Sorry for bad English. I'm running out of time and sanity.:(

Are you saying you want the two logic levels to be at 15 V and 20 V, respectively? Or that you want one logic level to be at 0 V and the other to be somewhere between 15 V and 20 V?

There are a variety of level-shifting ICs available, but it's not hard to create your own out of a few discrete components, most notably a pullup resistor and a pulldown transistor.

Yes. The logic input is 2,75 Volt and I need it to be somewhere between 15V to 20V.
Can I use a cmos chip for this?

Look at mouser.com for IR2110 chips.
Or just...
http://www.findchips.com/search/IR2110 and it will give you a lot of on line suppliers.
Even Ebay brought up a lot of entries.
have a good look at the data sheets and app notes.

There is this little board...

It looks interesting. The circuit in the PDF shows how you hook the chips up.

Omg that's exactly what I need. Thank you,

Omg I can try it out. Thanks a lot!
