Aim:To develop a compact and highly efficient Emergency LED driver.Objectives:1. Learn of and experiment with the existing technology utilized in Tridonic Emergency LED Drivers to improve understanding of the device.2. Identify a more efficient type of DC-DC converter which can be implemented and investigate the feasibility of implementing said DC-DC Converter while considering cost.3. Identify methods to reduce the size of the driver while considering cost. Potential future objective depending on progress of project:4. Investigate the optimal use of conventional and future energy storage options - Key Milestone:By the end of the first year, become accustomed with Tridonic Emergency LED drivers and learn more of Advanced Power Electronics through studying MSc/PhD level University modules. Research existing driver technology, including that of competitors. Begin to identify and experiment with potential methods to improve the efficiency of the driver to up to 90%, while considering the cost.A number of areas have been identified by Tridonic as being of interest for improving their emergency lighting drivers. Firstly, the efficiency of the driver will be investigated, with the potential use of different types of DC-DC Converters to reduces losses and improving the accuracy of current sensors. Following from this, an investigation into improving the form factor of the driver, with the use of smaller relays to reduce the height of the driver, allowing a smaller form and other more compact components. Improving the efficiency in the previous step may also reduce the required battery cell count while maintaining the same run time for a full charge. Finally, if the first two areas have yielded sufficient results, an investigation into the energy storage will be conducted. This includes the method of charging, the use of existing batteries with higher energy densities such as LFP and LTO and future/developing energy storage options such as Supercapacitors.
