Power factor reaction of CLC of CRC filter

Wes Marquenie · 7th June 2003, 03:10 PM

What is the reaction of the power factor with a CLC or CRC filter?

With a normal C filter the current flow from the mains will look like spikes, instead of a normal sine wave because there can only flow current if U(cap) < U(source).
How will this look like with a CLC or CRC filter?

in laymans terms a filter smoothes out spikes that you may see through a scope etc....I always have found that any P/s is better with a preloaded (resistive) design...my choice has always been a LC design...but thats my preference and it works for me

The peak current through the diodes is less and lasts for a slightly longer period of time. This puts less stress on the diodes and the first capacitor.

Without hurting anyone's feelings

may I suggest the use of the Duncan amp PS simulation program? It's free, easy and works well.

Grataku....where may we find this program...I`d like to give it a go???

Both types will improve the power factor. I believe the CLC
type will do it with somewhat greater efficiency.
