Sampling gain effect in buck converter
Pulse width modulation used in the control of power supplies essentially causes a phase delay in the loop, similar to the sampling delay in a pure digital system. When the inernal ramp voltage reaches ...

Sampling gain effect in buck converter
Let me try to give a simple answer to this question. Current-mode-controlled converters are made of two loops: an inner current loop and an outer loop which ensures voltage regulation. The error or ...

How to reduce gain margin to finite value?
I would prefer to call the gain margin in that plot "undefined" rather than "infinite".
When gain is measured as Vout/Vin the gain margin is defined as the factor by which you have ...

How to reduce gain margin to finite value?
The infinite gain margin becomes obvious by looking at the bode plots. The phase of the system lies between 0° and -90°, therefore the 'critical' phase of +/-180° is never reached. Speaking in terms ...

SIMPLIS - Buck CM from C. Basso Website
The circuits I provide in my 90+ ready-made templates are simplified versions of what a real controller would do. It is for clarity reasons, so that everyone can understand the operating flow, but ...

Unit of integral windup reset parameter?
There is an integral parameter \$k_i\$, with units of seconds.
There is a reset parameter \$\frac{1}{k_i}\$, with units of resets/minute.
There is no parameter integral windup reset.

Can the graphoanalytic method of synthesizing controllers by Bode plots (by lead and lag elements) be used for non-minimal-phase systems? If not, why?
If we use the Bode diagram to determine the stability characteristics of the closed loop, the Bode diagram for the open loop (loop gain) is examined for different controllers. In this context, the ...

How can I solve this (convolution) integral?
In the 3rd step, the integral from 0 to t includes negative values of t, but both starting signals are zero for negative t.
