A well construction system with motor equipment having at least one of a drawworks motor, a top drive motor, or a combination thereof, and an electrical power system having a power recovery and regeneration system. The power recovery and regeneration system includes at least one energy storage device that is not a capacitor bank. The well construction system may be operated by generating AC power that is made available on an AC node, converting AC power available on the AC node to DC power available on a DC node, storing energy based on DC power available on the DC node by the power recovery and regeneration system, and regenerating the stored energy from the power recovery and regeneration system to AC power, DC power, or a combination thereof for consumption by an electrical consumer of the well construction system.

Electrical power generation and distribution system with power recovery and regeneration

Systems and methods for dissipating heat from an electrical component using an external structure of a trailer or shed as a heat sink are disclosed. A heat-producing electrical component such as a variable frequency drive (VFD) using an insulated-gate bipolar transistor (IGBT) is housed in a trailer and is thermally coupled to an exterior wall of the trailer to use the wall as a heat sink to dissipate heat from the VFD and IGBT. An adapter can be used to couple VFDs and IGBTs of different sizes and configurations to a support site on the exterior wall.
