Peak Current Controller
Purpose
Implement peak current mode control
Library
Control / Modulators
Description
This block implements current mode control in a switching converter. At the
beginning of each switching cycle, the output is set. When the input exceeds
the
input, the output is reset.
Parameters
- Switching frequency
- The switching frequency of the output signal.
- Minimum duty cycle
- This sets the minimum time the output remains on for at the beginning of each switching period. This value must be non-negative and less than the maximum duty cycle.
- Maximum duty cycle
- This defines the maximum permissible duty cycle of the
switch output. If
, the output will turn off if the duty cycle exceeds this maximum value. The maximum duty cycle must be less than 100 %.
- Slope compensation
- Slope compensation can be applied to ensure stability when
the output duty cycle exceeds 50 %. Entering a parameter,
, reduces
during each switching cycle as follows:
, where
is the time elapsed from the start of the switching cycle and
is the switching period. Slope compensation can be omitted by setting
to 0.
