Filter Inductor

This inductor design was developed as a DC link filter inductor for an advanced power system, high power, PWM inverter. The unit operates with a continuous coolant temperature of 90ºC for hybrid vehicle applications. The embedded cold plate is electrical isolated from the inductor winding, and vacuum encapsulated in a thermally filled epoxy.
