Development of the power flow controller<\/h1>\n<\/div>\n<\/div>\n\n\n\n

New Year 2021 arrives \ud83c\udf86, so we are accelerating the work in MoReSiC – Project<\/strong><\/a>! Now we would give you a little taste of the task which include development of the power flow controller.<\/p>\n\n\n\n

The main objective of this task is to analyze all possible operation modes and develop the power flow control algorithm taking into account requested power from connected vehicles, state of the energy storage and performance of the power converters (estimated power losses), and finally design the digital control system and implement the algorithm.<\/p>\n\n\n\n

\ud83d\udcf6 To effectively manage the power flow appropriate #communication<\/strong> interface, ensuring low latency and high reliability, will be analyzed and implemented. External communication for remote monitoring and control will also be provided.<\/p>\n\n\n\n

\ud83d\udd04 Another important task is to elaborate #controlalgorithm<\/strong> to stabilize voltages in three wire DC distribution bus in different operating modes, especially in transient states.<\/p>\n\n\n\n

\u2611 Furthermore, after full capability of the controller in all power modes will be achieved the #digitalcontrolsystem<\/strong> will be designed.<\/p>\n\n\n\n

\u2705 Finally, the last part will consider implementing the developed algorithm into the designed control system so it is ready for #hardwaretesting<\/strong>.<\/p>\n\n\n\n

SiC-based power electronics submodules<\/h1>\n<\/div>\n<\/div>\n\n\n\n

2\ufe0f\u20e3 The second task is named \u201cSiC-based #powerelectronics<\/strong> submodules\u201d. This will be a key component for the realization of the entire MoReSiC – Project. This basic unit will provide the opportunity to implement the main assumptions of the system: #modular<\/strong> construction and easy #reconfigurability<\/strong>.<\/p>\n\n\n\n

\u2757 The main objective of this task is to conduct research aiming in development of a highly-optimized multilevel submodule with 1.2kV rated SiC power devices. The submodule will contain four switches with #SiCMOSFET <\/strong>and #Schottkydiodes<\/strong>, DC capacitors, gate drivers and air-forced cooling system.<\/p>\n\n\n\n

\ud83d\udcd1 The developed unit should work up to maximum DC side voltage of 800 V and RMS currents up to 30 A. All junction temperatures will be kept below 100 \u00b0C by suitable cooling and control system. Gate drivers are expected to provide typical protection functions: overcurrent & overtemperature protection as well as gate supply monitoring and the generation of dead-times. Finally, isolation between the submodule and control system above 3.4 kV (50Hz, 1 minute test).<\/p>\n\n\n\n

The task will be conducted by Markel team supported by Politechnika Warszawska<\/strong><\/a> PhD student. The task will be managed by Rados\u0142aw Sobieski, who is head of Markel\u2019s R&D department.<\/p>\n\n\n\n
