Designing a closed-loop, controlled power supply or motor-control system presents two main challenges. First, the design requires sending feedback voltage or current information across an isolation ...

Average current-mode control, as shown in Figure 1, is common in continuous-conduction-mode (CCM) power factor correction (PFC). It has two loops: a voltage loop that works as an outer loop and a ...

A new series of digital power controllers from Microchip integrate precise real-time control, rich analog peripherals, and ...

Discrete dynamics systems; discrete models of continuous systems feedback and digital controllers; analog-digital conversion; digital control design including PID, lead-lag, deadbeat, and model ...

Mixed-signal designs combine the most powerful features and advantages of both analog and digital circuitry. One common mixed-signal architecture is a chain of analog signal blocks, each controlled by ...
