Abstract
A digital power controller (DPC, 1) controls an SMPC power stage (2). The DPC (1) interfaces with the SMPC power stage (2), and it has a system-on-a-chip (SoC) architecture including a digital signal processor (DSP, 5) for real-time control of SMPC outputs (such as output voltage) and a RISC processor (CPU, 6). An ADC (7) receives sense signals and routes them to the DSP (5), and a DPWM circuit (8) drives the SMPC. Communication with the CPU (6) is via a bus (10). The CPU (6) features include fault management and data transfers to the DSP co-processors and other peripheral blocks.
Claims28
A digital power controller for controlling a power converter, the controller comprising a CPU, a bus, and peripheral devices communicating with the CPU via the bus, said peripheral devices including a co-processor executing control algorithms, an ADC receiving power converter sense signals, and a modulator providing output drive signals to the power converter.
