Full Digital Power With a dsPIC® DSC
For the highest performance, dsPIC® Digital Signal Controllers (DSCs) are designed to run powerful algorithms to maximize efficiency across widely varying load and environmental conditions. They have the performance to close the control loop using algorithms implemented in firmware. Fully digital power supplies are a competitive necessity in applications where efficiency requirements are stringent, transient response is critical and monitoring/reporting are mandatory for maximum uptime. This approach is ideal for server, networking and telecom infrastructure equipment, renewable energy hardware and wireless power applications.
dsPIC DSCs with Advanced Peripherals for Digital Power Control
A high-performance DSP engine and specialized peripherals are essential when you are implementing advanced software digital control loops for power applications. dsPIC DSCs feature a high-performance CPU and rich peripherals to create advanced power conversion designs with minimal requirements for external circuitry. The DSP engine performs single-cycle MAC with up to 40 bits of resolution, data saturation, zero overhead looping and barrel shifting to support fast control loop execution. Peripherals, such as high-speed PWM generators, ADCs, Programmable Gain Amplifiers (PGAs) and high-speed analog comparators can be tied together using an internal configurable control fabric so they can interact directly with one another, resulting in stunning performance gains in digital power applications.

Digital Power Starter Kit Demonstration – MASTERs Conference 2015
This is a Live Update demonstration of the power supply firmware using Microchip’s new dsPIC33EP ‘GS’ devices. These devices contain two flash partitions such that programming of the inactive partition can occur without stalling the CPU which then leads to continuous regulation of the power supply (i.e. no down time to update PSU firmware). The demonstration shows an extreme case where the compensator is being changed from an poorly designed 2P2Z compensator to a properly designed 3P3Z compensator.
