| Current is carried through busbars, or wire bondings, as a supply line
of electrical power.Parts, such as components used in inverters to handle
variable frequencies, produce an increased amount of heat due to the resistance
cause by a skin effect that increases as the frequency of the current flowing
through the circuit gets higher.A design that accounts for the heat and
temperature distribution of each frequency is vital because the excess
heat causes a reduction in efficiency or damages the device.The temperature
distribution can be evaluated by treating the Joule losses obtained from
the magnetic field analysis as the heat source.This example presents the
use of a coupled magnetic field and thermal analyses to obtain the temperature
distribution in a busbar when the frequency of the power supply is changed. |

Voltage surges can damage the components in electrical equipment such as
an inverter. It is important to reduce busbar inductance to protect the
electrical equipment since it can be a cause of surges. This case study
shows the current distribution and frequency versus the inductance characteristic
of the busbar.
