| Abstract: | ecause of the application environment in coal mines , there are strict explosion proof require- ments on charger. So, it challenges the heat dissipate of the machine. The only solution is to improve the efficiency. Half--bridge LLC resonant be used to improve the efficiency of explosion proof charger in coal mines, so the novel explosion proof charger is developed. Experiments showed that the full load efficiency of the explosion proof charger up to 95.2 %. |
