Output characteristics of DC-DC converter with DSP control

This paper presents the output characteristics and design criterion of the 100 kHz high-speed DC-DC power converter with the DSP control. The circuit configuration and operation principle of this circuit is described. Also, the regulation characteristics in the PID control are examined theoretically and experimentally. As a result, the relationship between the regulation characteristics of the DC-DC converter and the quantization width of the A-D signal converter is clarified, and then the design criterion of the 100 kHz high-speed DC-DC converter with the DSP control is defined.
