摘要： The invention relates to a power converter stage (2) for providing power supply to a power converter controller (3), a power converter controller (3) for such power converter stage (2), a power converter (1) including such power converter stage (2) and such power converter controller (3), a method for providing power to a controller (3) of a power converter (1) and a software product for controlling a power converter (1). In order to provide for auxiliary power supply for control circuitry of a power converter (1) during all operation modes of the power converter (1) while avoiding additional costs involved with providing a dedicated control power supply fed from bus voltage, it is proposed that power stored in power storing means (4, 5) included in a power converter stage (2) or more generally in a power converter (1) are used for supply to the controller (3) even if the power converter is in stand-by mode, as a transfer of power between such power storing means (4,5) through a primary inductance (6) may be used for providing also for a power transfer to a secondary inductance (7), which then supplies the controller (3).

摘要： A control strategy for operating a plurality of prime power sources during propulsion, idling and braking and is applicable to large systems such as trucks, ships, cranes and locomotives utilizing diesel engines, gas turbine engines, other types of internal combustion engines, fuel cells or combinations of these that require substantial power and low emissions utilizing multiple power plant combinations. It is directed at a general control strategy for multi-engine systems where the power systems need not be of the same type or power rating and may even use different fuels. It is based on a common DC bus electrical architecture so that prime power sources need not be synchronized.

摘要： A DC-DC converter reduces a surge voltage developed across a switching element (30) in making the voltage conversion with the use of a transformer (20) inherently having considerable leakage. A snubber circuit is included to absorb the surge energy and transferring it to a load, or output end of the converter, reducing the surge voltage across the switching element (30). A snubber capacitor (51) is provided to absorb the surge energy developed by the transformer (20) when the switching element (30) is off. Thus absorbed energy is collected in a storage capacitor (53) through a reactor (54) while the switching element (30) is on and off, and is then transferred from the storage capacitor (53) to the load, i.e., the output side of the converter, leaving only a minimum voltage being applied across the switching element (30).

摘要： An alternator system having an alternating current voltage source includes a rectifier coupled to the voltage source, a sensor coupled to the voltage source and an engine and a control circuit coupled to the voltage source, the rectifier and the sensor. The control circuit provides control signals to the rectifier and the voltage source. The alternator system further includes a fault protection controller coupled to an output of the alternator system and coupled to the control circuit. The rectifier operates such that the alternator system provides a load match which results in output power levels which are relatively high compared with output power levels of conventional alternator systems and the fault protection controller operates under fault conditions (e.g. load dump), and overrides the other controllers in the alternator system based on output voltage when a load dump occurs.

摘要： An alternator system having an alternating current (ac) voltage source includes a switched-mode rectifier (SMR) coupled to the ac voltage source and having an output port coupled to an output of the alternator system, and a controller coupled to said switched-mode rectifier so as to provide a controlled pulse sequence synchronized with an angular rotor position of the (ac) voltage source to activate and deactivate the switched-mode rectifier. The controller further includes a PWM generator having a first input to receive a total duty ratio signal synchronized with an angular rotor position of the (ac) voltage source. The switched mode rectifiers are controlled to increase power output levels at lower speeds near idle. The controller combines improved idle speed power output levels with load matching improvements from PWM control for more efficient operation when compared to circuits using conventional control or PWM load matching control alone.
