Digital Control of Power Supplies
The progress of innovation driven by technology in past decades creates a vast number of applications to support our needs for electrical equipment with standard or advanced functions. The overwhelming majority of devices are powered from an AC power sources, even those with batteries need to be recharged. New concepts of smart systems are to be as intelligent as possible. This provided design engineers opportunities to use internal components with expanded features e.g. telemetry, fault logging, external control or easy adjustment. Integration of digital control into the AC-DC power supply is an under-utilized next step to capitalize on the opportunities mentioned above. Digital control of a power supply can be broken down into two perspectives, external communication and control of the power supply (On/Off, setting adjustments etc.) and internal control (feedback loop, dynamic behavior, response to AC mains changes and output load changes etc.) of the power supply to enhance performance and capability of the “Black Box” power supply. This application note will discuss both perspectives and highlight the considerations and trade-off made in the product definition phase.
