How is digital control implemented in power converters?

Digital control uses DSP/microcontroller for PWM generation and feedback loops. Key considerations: sampling rate (typically 10-20x switching frequency), ADC timing (synchronize to avoid switching noise), computational latency (adds phase delay affecting stability), PWM resolution (higher frequency needs finer resolution), and fixed-point vs floating-point (precision vs speed tradeoffs). Control algorithms include: digital PID (discretized with Tustin or backward Euler), state-space controllers, predictive control, and adaptive algorithms. Debug capabilities (real-time data logging, oscilloscope triggers) are essential for development.
