The invention discloses an embedded DC-DC
digital converter software closed-loop debugging
system and method, and in the development of a DC-DC
digital converter,
software closed-loop debugging is realized by embedding a power
electronic switch network and digital filtering
simulation in an embedded circuit. The
system outputs an electrical relation transformation formula based on a duty ratio
signal D, performs DC-DC
simulation transformation on an input
voltage to obtain a transformation
voltage, filters the transformation
voltage through a
simulation LC
digital filter to obtain an output voltage, samples voltage and current feedback values after simulation application, and performs closed-loop regulation on the duty ratio
signal D according to the voltage and current feedback values. According to the invention, a power
electronic switch network and digital filtering
software are embedded on the embedded circuit board for simulation, so that the limitation that software closed-loop debugging can only be carried out after hardware is completed in existing research and development is broken, closed-loop debugging of a DC-
DC converter core
control algorithm is carried out in advance,
software development and hardware development are synchronously promoted, and the development efficiency is improved.
Software research and development stagnation caused by a hardware period is avoided, and the overall research and
development period is greatly shortened.
