Today’s electronic power architectures demand high power density even in the presence of increased heat generated by various devices in these designs. The challenge is to cool those devices with a cost-efficient component known as the heat sink. Creating an optimally designed heat sink will improve a power supply’s power density, device reliability, performance, and service life.
Power density is defined as the ratio of power-converter output power to converter volume. This is an important parameter characterizing the compactness of power electronic systems.
