Renesas Electronics 1kW Off-Board Electric Vehicle (EV) Charger

Renesas Electronics 1kW Off-Board Electric Vehicle (EV) Charger is a reference design for EVs based on the ISL6730 PFC Controller and the RC66T Microcontroller. As e-Mobility increasingly becomes part of daily life, there is a growing need for more efficient charging solutions. High-power off-board chargers are the functional blocks for supporting battery pack solutions. This charger combination works on a universal input range. It uses a high-end MCU to control power factor correction (PFC) and manage the zero voltage switching (ZVS) with the half-bridge switching converter sitting on the secondary side of the system. The Renesas RC66T MCU offers better and more secure control of the output parameters, and its CAN interface helps customers to target a wide range of customer bases.

Features

  • PFC control using the ISL6730 PFC controller, which offers adaptive control that enables extremely low THD and high PF
  • Digital controller protections and features like UVLO, OVP, OCP, OTP, and inrush current
  • Difficult to copy as the ZVS stage is controlled via the MCU
  • Upgradable to higher current systems with an option to add sync rectification on the secondary side
  • Battery health implementation

Applications

  • High voltage battery packs (48V Mobility Solution)
  • AC-DC high voltage or wattage loads
  • Light Electric Vehicles (LEV) as an off-board charger
  • Lawn and garden equipment
  • Industrial supplies
