摘要: A discrete proportional-integral-differential controller, driven from a sampling digital error amplifier, is used to penetrate quantized duty ratio control signal provide dynamic output voltage regulation for switching dc-to-dc power converters. The frequency of the PID controller equal converter, so may be at different frequencies without recompensation. Digital techniques are also current limiting, soft-start, undervoltage lockout, overvoltage shutdown, and master-clear indications.
