For this application, a simple ramp generator can be realized
with a minimum number of active and passive components.
A ramp having good linearity is not required for proportional
operation because of the nonlinearity of the thermal system
and the closed loop type of control. In the circuit shown in
Figure 32, the ramp voltage is generated when the capacitor
C
the ramp is determined by resistors R
