I have built an AC/AC cuk converter for an assignment I am doing. It works as such, I provide 50V AC in and I get an adjustable voltage out from 0V to 50V AC, depending on the duty cycle of the PWM that I gate to the MOSFETs. It is designed to supply a max of 1A rms to the load. I have included a schematic below, drive circuit as not been shown. IMG

It works extacly as I have explained. However, I would like to incorporate some sort of rudementry simple short circuit protection.

Any ideas would help, thanks.

  • \$\begingroup\$ Perhaps I may have foolishly included 'rudementry' & 'simple' into the question. Are there any ICs that would deal with short circuits? or perhaps a low circuit breaker? \$\endgroup\$

  • \$\begingroup\$ Is your goal to protect your components, or just to provide information that something bad may be about to happen? Should it be recoverable? Automatically? Manually but electronically (i.e. press a button rather than replace a fuse)? Etc. \$\endgroup\$

  • \$\begingroup\$ Protecting the components would be my primary goal. I would also prefer it to be recoverable in a manual sense (like press a button or turning it off/on..) \$\endgroup\$
