Abstract:

Fast charging is the key technology of the current small electric cars need to be addressed. This pa-per has developed a smart electric vehicle fast charger, the charger uses MC9S12XE100 microcontroller-based dual closed-loop control of a multi-mode adaptive charging mode for charging. Were the main circuit parameters, in-cluding power management selection, transformer design, circuit design to absorb and filter circuit design, PWM control circuit design, microcontroller core circuit design. Finally, the test proved that the design of the charger reaches the performance requirements, the main circuit topology and control circuit is feasible.

Key words: two stroke aero engines, linear parameter varying model, the average model, injection control, steady operating conditions, transient operating conditions
