International Classification:

F28D 1500

US Classification:

16510433

Abstract:

A system for temperature control of an electronic component includes a heat plate supporting the component; a heat plate temperature sensor; a fan capable of providing air for cooling the heat plate; and a fan control for using the heat plate temperature to control the operation of the fan to provide a substantially constant heat plate temperature. The system can further include a heat pipe assembly having fins and coupled to the heat plate with the fan capable of providing air to the fins. The heat pipe assembly can include at least two heat pipes each having first ends coupled to the heat plate and second ends situated in a condensation section where at least one of the heat pipes has a different working fluid than an other. A switch temperature or load current sensor can be coupled to the heat plate and supply data to a switch controller for receiving the switch temperature, determining whether the temperature or load current has changed, and adjusting a switching frequency of the at least one electronic switch device in response to any change of the switch temperature. A bus layer can be situated adjacent the component and selectively coated with an insulating material and studs can mechanically and electrically coupling the bus layer and a printed circuit board to the component.

H02M 5/42

Abstract:

An electrical power system includes a cluster of electrical power subsystems, each of the electrical power subsystems including a power converter electrically coupled to a generator having a generator rotor and a generator stator. Each of the electrical power subsystems defines a stator power path and a converter power path for providing power to the power grid, the converter power path including a partial power transformer. Each of the electrical power subsystems further includes a low voltage distribution panel electrically coupled to the converter power path, a first switch on the stator power path, and a second switch on the converter power path.
