TRANSFER FUNCTIONS - poles and zeroes for all common topologies

This data will be added to systematically for more conditions such as discontinuous conduction modes.

Vramp = amplitude of sawtooth ramp  

Ri = Rsense x Current gain eg. Rsense x 100 for 100:1 sense transformer  

Optimum slope compensation assumed in each case  

D = Duty cycle  

f = operating frequency  

Np = transformer primary turns  

Ns = transformer secondary turns  

Ls = Shim inductor in PSFB
