Boost mode

In certain cases, it may be necessary for the device to automatically allow higher power or higher currents. This is possible by activating the boost mode in the device (for details on boost mode, see the "Power and Energy Solutions" device manual). If the MOVI-C^® CONTROLLER is to control boost mode, it must be activated via xActivateBoost in the device and the minimum application limit must be set to "0 V". Depending on the operating state of the system, it may be necessary to initially deactivate boost mode, e.g. when charging the energy storage unit for the first time, which should be done at low power.

If the system is in normal operation, boost mode can be activated via xActivateBoost and thus released again. If the voltage drops below the minimum voltage of the defined operating range due to high load (in the example in the following chapter, this is 450 V), the device releases the parameterized application limits of the power and currents regardless of the MOVI-C^® CONTROLLER setting, so that a higher current/power flow may be possible to provide additional support for the DC link.
