On-Board Charger
On-board chargers (OBCs) are a critical component in electric and plug-in hybrid vehicles, converting external AC power into DC power to charge the vehicle battery safely and efficiently. As EV adoption continues to grow, OBC systems must deliver higher charging efficiency, improved reliability, and compact power designs capable of operating under demanding automotive conditions. These systems require stable power conversion and thermal performance while handling high voltages and continuous charging loads.
Capacitors to support Onboard chargers should have the following characteristics:
Capacitors to support Onboard chargers should have the following characteristics:
- High capacitance
- High ripple current
- Low ESR
- Long life
- High voltage
Here are some examples of suggestions from our product lineup.

Here are recommended part series for this application:
LGA
The LGA series offers high capacitance and ripple current designed to meet the requirements of on-board EV and PHEV chargers.
LGN
The LGN series capacitors can withstand 3,000 hours of rated ripple current at 105°C, operating over a temperature range of -40°C to 105°C (160 V to 250 V) or -25°C to 105°C (350 V to 600 V).
LGX
The LGX series offers capacitors with a long life assurance of 5,000 hours at 105°C, suitable for rectifier circuits in inverters and switching power supplies.
