Double pole, double zero: incorrect plot?
I can't seem to find where I'm going wrong here. Suppose I want a double pole, double zero system that looks like this:
$$ \dfrac{\left(1+\dfrac{s}{\omega_z}\right)\left(1+\dfrac{s}{\omega_z}\right)}{\...

Controller for boost converter
I'm trying to design a controller for a boost converter by the "shaping loop gain" method as in the Fundamentals of Power Electronics textbook by Ericson and Maksimovic.
I see that there is ...

Slope compensation of MAX17498
I want to use MAX17498 in boost mode.
I have a problem setting the slope compensation. The slope (as I understand) is the gradient of the inductor's current ramp. The unit is [A/s] or [A/us]. However,...

Adjustable non-inverting Buck-Boost converter failing right after starting in boost-mode
I am designing an adjustable non-inverting buck-boost converter based on LM5176 chip. Adjusting is done by DAC via feedback network, more on that technique can be found here.
The input voltage is 32V ...

Calculating values for compensation network (boost converter RC+C network)
I'm trying to build a boost converter with current mode PWM control, but I'm stuck at selecting capacitor and resistor values for compensation. I'm using a LT1619 as the controller IC:
simulate this ...
