Characteristic function of rectifier regulation

Extends from Modelica.Blocks.Interfaces.SISO (Single Input Single Output continuous control block).

Information

This characteristic function is defined by five different modes :
  • Two constant modes (below 0 and above 1)
  • Two linear modes (between 0 and ULow, between UHigh and 1)
  • One non-linear mode (between ULow and UHigh)
The function is continuous thanks to the adjusted coefficients A1 and A2.

If A1 * A2 = 1, the characteristic is a symmetry : for any value of u between 0 and 1, y(y(u)) = u.

With the default values of UHigh and ULow :
  • A1 = 1 / sqrt(3)
  • A2 = sqrt(3)
  • The characteristic is thus a symmetry
