[0002] There are usually several conductive connection devices in an electric drive, and may include one or more chokes. A choke can utilize the inductance effect to limit the change of current, such as reducing current fluctuations and electromagnetic interference. Thus, a choke can limit the change of current in an AC circuit, and is particularly effective in suppressing high-frequency noise. A choke generally includes a coil and a magnetic core, and is thus also called an iron-core inductor. The coil can be formed by a wire. The coil of the choke can be electrically connected in the circuit. Summary of the Invention
