Piecewise model for SCR, i have no ideaeven search from google

[emperror123]

dear all,

i have been carried out the experiment about SCR, but some question come across, which is piecewise model of SCR in on state, what is the meaning of it, is it show in I-V characteristics, or any other thing need to be find before obtain piecewise model in on state??

thank, and ur answer is much appreciated

This will give you a primer on SCR ( PNPN junction)

hi SunnySkyguy

is the piecewise model is based on I-V graph, i know how the SCR works, but not understanding piecewise model of SCR, unable get it from google or any other source,

thank hope to get more detail of it
