Implementing advanced
software digital c
ontrol loops for
powerapplications requires a high-performance DSP engine along with specialized peripherals. The high-performance CPU and rich peripherals of the dsPIC DSC devices enable solutions that do not require much in the way of external support chips. In addition to the space and cost-saving benefits found in the dsPIC DSC solutions, special features enable advanced power conversion. The DSP engine
canperform single-cycle MAC with data saturation, zero overhead loo
ping and barrel shifting required to support f
ast control loop execution.
These devices include peripherals specifically designed for power conversion. Peripherals such as a highspeed PWM, ADC and analog comparators can be tied together using an internal configurable control fabric that enables them to interact directly with one another, resulting in stunning performance gains in digital power applications.
