TDK Unveils New Power Capacitors for Hybrid or Electric Drives of Motor Vehicles
TDK-EPC, a group company of TDK Corporation has unveiled a new Power Capacitor Chip (PCC), for an ideal DC-link circuit solution of the electric drives of motor vehicles. The PCCs are characterized by a volume fill factor of nearly 1 and fit perfectly onto the IGBT (Insulated Gate Bipolar Transistor) modules HybridPACK1 (up to 20 kW) and HybridPACK2 (up to 90 kW) both developed by Infineon Technologies. The rated voltage of the PCCs is 450 V DC, with capacitance of 300 and 500 uF. Furthermore, PCCs feature a low ESL of no more than 15 and 25 nH, respectively. Their ESR is a maximum of 1 m ohm. The normal operating temperature of PCCs is between -40 to 110 degrees Celsius but they can withstand for a brief period at a temperature of 125 degrees Celsius. The PCCs average operating life span is 15,000 hours. Additionally, the PCCs are self healing, so at the event of breakdowns of the film during an overload, there is no short circuit or destruction of the capacitor.
