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

Serving to customers choose the proper 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 executed, the instrument shows a listing of appropriate elements for the consumer. If a parallel connection is required, the variety of elements required can be proven. An important 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 secure. Within the occasion of an inner brief circuit within the system when it’s switched on, this element shortly 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 – equivalent to in on-board charging circuits and for the charging and discharging of DC hyperlink capacitors in hybrid and electrical drives.

The instrument is on the market on-line from TDK Company and doesn’t should be downloaded.
