Figure 6. Buck converter described in Simulink 3.1.3. Closed-loop buck converter A closed-loop buck converter circuit is illustrated in figure 7 a. The measurement of the output voltage is realized by 2 resistances R1 and R2. The regulation is achieved by a PID controller. Simulink model ...
A transformer isolated, Power Factor Corrected (PFC) AC-DC power converter comprises a main power path which is buck derived, and most of the power passes through a single power stage to the output. A parallel path in the secondary circuit shunts current to a storage capacitor during the tim...
The control V/f algorithms based on unity power factor (UPF) calculation are simulated and experimentally verified in [48,49]. A similar technique is applied and compared with FOC in [50,51], where active flux observer and MTPA are used. Stable V/f control with UPF was compared to back...
