摘要： A series-parallel rectifier system and methodology, employing multiple parallel rectification paths is disclosed. The system includes a dual winding AC power supply and a rectifier apparatus coupled to the AC power supply. The rectifier apparatus is comprised of rectifier legs interconnected in a parallel circuit relationship, where each leg comprises several rectifiers including a connection in series and oriented to conduct current from a negative DC bus to a positive DC bus. Bypass legs comprising two rectifiers including a connection in series and oriented so as to conduct current from said negative DC bus to said positive DC bus are added in place of redundant rectifier legs and interconnected with the AC power supply.

摘要： A shoot-through protection system for an electric power generating system including a synchronous generator, a bridge rectifier coupled to an output of the generator for converting alternating current (AC) from the generator to direct current (DC) at a rectifier output, and at least one inverter coupled to the rectifier output for converting the DC output to a controlled frequency AC output for application to a load. The generator has a separately excited field winding in which the magnitude of field excitation controls the voltage output of the generator. A microprocessor-based controller regulates generator field excitation in a manner to control the DC output of the rectifier. The generator is protected from a shoot-through in the inverter by detecting a sustained voltage drop in the rectifier DC output and reversing generator field excitation in response to such a voltage drop to rapidly drive generator output voltage to substantially zero volts.

摘要： A method for providing thermal protection for forced air cooled power electronic semiconductors without direct measurement of semiconductor temperature, the semiconductors being mounted on a heat sink over which cooling air is blown includes the steps of computing the cooling air mass flow rate, creating an electronic model of the semiconductor/heat sink combination and estimating the semiconductor junction temperature from the mass flow rate and model. The cooling mass flow rate is determined by measuring the temperature of the cooling air prior to passage over the heat sink, measuring atmospheric pressure of the cooling air, determining the volumetric air flow rate of the cooling air and computing, from the cooling air temperature, pressure and volumetric flow rate, the cooling air mass flow rate. Power dissipation in the semiconductors is then computed and heat sink and semiconductor temperatures are estimated from power dissipation and cooling air mass flow rate. Semiconductor power dissipation is limited so as to restrict semiconductor temperature to a safe operating value.

摘要： A control system includes a controller and an energy management system. The controller is onboard a vehicle that includes motors and an onboard energy storage device that powers the motors. The energy management system calculates estimated electric loads of powering the motors over one or more segments of a trip according to designated operational settings of a trip plan. The energy management system also determines a demanded amount of electric energy for powering the vehicle based on the estimated electric loads. The demanded amount of electric energy is based on a stored amount of electric energy in the onboard storage device. The energy management system communicates the demanded amount of electric energy to one or more of plural wayside stations disposed along the route so that the wayside stations have sufficient electric energy to charge the onboard energy storage device with the electric energy to meet the estimated electric loads.
