Title: INTEGRATED POWER AND ELECTRONICS UNIT FOR DRILLING MACHINE
Abstract:
An integrated power and electronics unit (IPEU) operable for providing output power for driving an electric motor of a drilling rig machine. The IPEU comprises a housing, a radiator, and a VFD. The radiator is mounted within the housing and comprises radiating members each extending through an opening in the housing. The VFD comprises insulated-gate bipolar transistor devices (IGBTs) operable to convert input power to the output power. The IGBTs are coupled to the radiator within the housing such that heat generated by the IGBTs is transferred out of the housing via the radiator. The VFD also comprises a controller operable to control the IGBTs.
