Parameter conversion for stability of digitally controlled converter
A DC-DC converter is digitally controlled by detecting an output of the converter; comparing the output to a target value to determine an error value; calculating a control parameter based on the error value in which an output control target is a linear function of the control parameter; converting...

| description | A DC-DC converter is digitally controlled by detecting an output of the converter; comparing the output to a target value to determine an error value; calculating a control parameter based on the error value in which an output control target is a linear function of the control parameter; converting the control parameter to a converter control parameter; and, based on the converter control parameter, generating a pulse signal to control a power switch of the DC-DC converter. The output control target may be an output voltage, an output current, or an output power. Calculating the control parameter may include using equations that provide either proportional-integral-derivative (PID) control or proportional-integral (PI) control. The DC-DC converter may be a boost DC-DC converter. The pulse signal may provide duty control, on-time control, off-time control, frequency control, or phase-shift control. |
