It permits a developer to enter the parameters of the PTC inrush present limiter after which shows an inventory of appropriate elements

Serving to customers choose the appropriate PTC inrush present limiters (ICL) for a spread of various energy provide and converter topologies is a brand new, intuitive instrument.

It’s user-friendly because it permits a developer to enter enter the charging voltage and the utmost ambient temperature of the PTC inrush present limiter after specifying the circuit construction and the capacitor financial institution’s complete capacitance. After this has been achieved, the instrument shows an inventory of appropriate elements for the person. If a parallel connection is required, the variety of elements required can also be proven. A very powerful key figures are additionally proven, in addition to hyperlinks to service distributors that promote the PTC ICLs.

One important benefit of PTC inrush present limiters is the truth that they’re intrinsically protected. Within the occasion of an inside brief circuit within the machine when it’s switched on, this element rapidly limits the present to non-critical ranges. Moreover, this element ensures light charging of the DC hyperlink capacitors.

Along with their use in converters and energy provides for industrial and family electronics, PTC inrush present limiters are additionally used within the area of e-mobility – akin to in on-board charging circuits and for the charging and discharging of DC hyperlink capacitors in hybrid and electrical drives.

The instrument is accessible on-line from TDK Company and doesn’t must be downloaded.
