- Page 2 H-bridge converter with inductive load, and the controller employs a proportional-integral (PI) current control scheme. These subsystems can then be independently built on the PLECS RT Box either for Hardware-in-the-loop (HIL) testing of an external controller or for rapid control prototyping (RCP).

- Page 4 The controller subsystem, shown in Fig. 3, receives the sensed inductor current and the DC input voltage values in the Analog In blocks of the PLECS RT Box component library. These values are in- versely scaled to reverse the scaling applied at the Analog Out blocks of the “Plant” subsystem. The modulator modeled in the subsystem named “Right Leg Duty-Cycle”...
