water heater using SCR

[mariuszoll]

Hi,

I have to develop a circuit for water heating using SCRs. Since now, I haven't work with thyristors.
Could you help me please with some pieces of advice how to proceed with this topic?

Thank you.

Look at the websites of manufacturers of SCRs. There is PLENTY of information there. Look at onsemi, IXYS, etc.

I presume, you'll use anti-parallel SCR combinations as AC switch, functional equivalent to a triac but with different gate control. They are also available as module in a single package.

Heating applications are required to use full-wave switching by power quality standards.

For water heating you should use SCRs or Triacs with a zero-crossing start circuit to minimize EMI.
