| VTB provides valuable support for the PEBB program by validating new control algorithms for the ARCP circuit. The 150kW PEBB demonstrator currently being tested at NSWC Caderock division uses a modified Load Modulated Auxiliary Resonant Current (LMARC) controller. This controller has been modeled in VTB and can be operated in a number of modes. For example, the resonant current and the load current waveforms shown in figure (b) is simulated data generated while the controller was operated in the constant boost mode, while the waveforms in figure (c) shows the controller operating in the variable boost mode with pulse inhibit. Figure (a) illustrates how the LMARC controller appears in the VTB schematic editor. | ||

At present,
working in close cooperation with NSWC, research focuses on validating a new type of
controller for the PEBB in VTB. The new control scheme splits the control into three
distinct levels, (i) PEBB Hardware Manager (PHM) (ii) Universal PEBB Controller (UPC) and
(iii) the PEBB Application Controller (PAC), as illustrated in figure (d). This separation
of control components offers several advantages over the conventional LMARC controller:
