As electro mobility (e-mobility) increasingly becomes part of daily life, there is a growing need for more efficient charging solutions. EVs can help broaden the number of fuel choices available for transportation. EVs can also reduce the emissions that contribute to climate change and smog, improving public health and reducing ecological damage. Fueling with electricity offers some advantages that are not available in conventional internal combustion engine vehicles. Because electric motors react quickly, EVs are very responsive and have very good torque. EVs are often more digitally-connected than conventional vehicles, with many EV charging stations providing the option to control charging from a smartphone app. This design approach utilizes an active PFC and asymmetrical full-bridge ZVS converter, along with an RL78/G14 MCU for EV charger applications.

System Benefits:

  • Highly integrated MCU 
  • The ISL6731B provides adaptive control that enables extremely low THD and high PF without DSP
  • The RL78/G14 MCU allows users to implement working logic, protections, and features for the driver
  • Battery health implementation features
