Development platform for digital signal controllers

The board consists of two independent DC/DC synchronous buck converters and one independent DC/DC boost converter. It operates from input supply of +9-15V DC. This board can be controlled either by interfacing to 28- pin Starter Development board or to Explorer 16 Development Board.

The control boards provide closed-loop Proportional-Integral-Derivative (PID) control in the software to maintain the desired output voltage level. The dsPIC SMPS and Power Conversion family devices provide necessary memory and power supply peripherals which enables to build the control loops in software without the need for external circuit.

Performance measures that can be evaluated are: digital control loop performance of power conversion; dynamic load performance; multiphase buck and synchronous buck converter; parallel operation of two buck converters; and multiple output control with a single dsPIC33F GS SMPS device.
