We will work with the parameter values for inductance and capacitance already in our model, but it is important to note that we can easily change those values, run the simulation, and observe changes. In this video we will not discuss how the passive components were sized. Our control algorithm computes a PWM signal that drives the MOSFET of the boost converter. The outer loop controls the load voltage and the inner loop controls the inductor current. We can see the algorithm is a cascaded control loop architecture. We have modeled the digital control algorithm in this subsystem named Controls. This rectifier is connected to a digitally controlled boost converter and a resistive load rated at 400V. We have an AC source of 120V rms connected to a diode bridge rectifier. LetвЂ™s look at the different elements of the model.

Here, we have modeled a typical active power factor correction setup using blocks from Simscape Electrical and Simulink.

Plant linearization is achieved by injecting perturbations into the plant to estimate frequency response models for the inner and outer loops. YouвЂ™ll see how to use the PID Tuner from Simulink Control Design to tune the controller using outputs from a linearized plant model. The cascaded controller setup is modeled in Simulink and controls the inner inductor current loop and the outer voltage loop. The passive components like the diode bridge rectifier and the boost converter are modeled in Simscape Electricalв„ў. In this video, youвЂ™ll learn how to use Simulink В® to perform power factor correction by modeling a PFC boost converter and tuning controller gains to achieve a power factor near unity. Power factor correction (PFC) is a way of increasing a power supplyвЂ™s ability to deliver real power.
