Details of EVC series capacitor for power electronics

EVC is a monolithic ceramic capacitor series specialized for power electronics.
Conventionally, film capacitors and aluminum electrolytic capacitors have been used in power system electric circuits of electric vehicles and hybrid vehicles. Murata developed new elemental technologies to commercialize ceramic capacitors usable in power electronics applications. Replacing conventional capacitors by ceramic capacitors makes equipment smaller and able to handle high currents. EVC series was introduced in KERS (Kinetic Energy Recovery System) used in F1 racecars. Murata intends to widely promote solutions taking advantage of excellent potentials of the EVC series.

Features

  • Can be made smaller than film capacitors and aluminum electrolytic capacitors due to larger capacitance per unit volume.
  Film capacitor Aluminum electrolytic capacitor EVC series
Capacitance per unit volume (μF/c.c.) 1.2 1.9 2.4

(DC630V rated voltage equivalent. Measured for actual usage. In-house comparison.)

  • Less heat radiation and larger allowable ripple current due to low ESR, accommodating high current making it suitable to inverter circuits on-board.
  • Excellent surge suppression due to low ESL
