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.

目的：研制一种紧凑、高效的应急LED驱动电源。了解锐高应急LED驱动器中使用的现有技术并进行实验，以提高对设备的理解。2.确定一个更有效的类型的DC-DC转换器，可以实现和调查的可行性，同时考虑到成本的DC-DC转换器。确定在考虑成本的同时减小驱动程序大小的方法。潜在的未来目标取决于项目的进展：4.研究传统和未来能源存储选项的最佳使用-关键里程碑：在第一年年底之前，熟悉锐高应急LED驱动器，并通过学习MSc/PhD水平的大学模块来学习更多的先进电力电子技术。研究现有的驱动程序技术，包括竞争对手的技术。开始确定和试验潜在的方法，以提高效率的驱动器高达90%，同时考虑到成本。锐高已经确定了一些领域，以提高他们的应急照明驱动器的兴趣。首先，将研究驱动器的效率，可能使用不同类型的DC-DC转换器来降低损耗并提高电流传感器的精度。在此基础上，研究如何改善驱动器的外形，使用更小的继电器来降低驱动器的高度，从而实现更小的外形和其他更紧凑的组件。在前一步骤中提高效率还可以减少所需的电池单元数量，同时保持完全充电的相同运行时间。最后，如果前两个领域取得了足够的结果，将对储能进行调查。这包括充电方法，使用具有更高能量密度的现有电池，如LFP和LTO，以及未来/开发的能量存储选项，如超级电容器。
