Intelligent Power with Digital Feedback Loops

摘要

Market Factors are driving the development of intelligent power supplies that involve external control of the power supply and soft configuration in production. One way to achieve this is with digital feedback control of the power-conversion loop.rnPower-supply designers have employed microcontrollers (MCUs) in intelligent power supplies for communications, monitoring, control and deterministic functions, such as power sequencing, soft start and topology control. However, until recently, complete digital control of the power-conversion loop has been impractical, due to the lack of suitable cost-effective technology. With the advent of Digital Signal Controllers (DSCs) that contain specialised peripherals, complete digital control is now practical.
