Moddeling Load Dump Pulse 5a in LTSpice

[Jay_Diddy_B]

Hi,

The .func mod(x,y) {((x/y)-int(x/y))*y}

This is a user-defined function.

The function name is 'mod'

The input parameters are x and y.

{((x/y)-int(x/y))*y}

This mathematical describes the function

in this case it describes the modulo function, it returns the remainder after division.

mod(11,4) = 3

The SPICE variable time is the current simulation time.

so

mod(time,60) would generate a ramp that goes from 0-59.99999




Voltage source

The voltage source is the first time in the expression. In this case the voltage source is 28.
