Abstract

In order to realize safety power supply or charging to the electrical equipment used in coal mine; a novel safety charging mode with multi-load used in coal mine was analyzed. This system has realized wireless power transfer (WPT) to the equipment by applying electromagnetic induction theory. Take the charging system for searchlights used in coal mine as an example, the topology and operating principle were introduced, and the system was optimized; meanwhile, a smart Ni-MH battery charging circuit was also developed. Finally, the theoretical analysis was verified by an experiment.
