摘要:
Fuel cell systems and control methods including a fuel cell and a second energy source, such as a battery that is adapted to supplement the fuel cell. In addition, the fuel cell system utilizes a single bipolar switching module, such as an IGBT six pack module that is configured to implement a DC/DC converter, such as a DC/DC boost converter, for both the fuel cell and the battery. The fuel cell system also makes use of a controller that is configured to control either or both of input current and output voltage of the DC/DC converter.
摘要:
Provided is a method and apparatus for simulating the behavior and operation of a three-phase induction machine. The present invention provides for a digital simulating device for simulating the behavior and operation of three-phase induction machines in accordance with selected parameters. There is further provided a computer modeling method for behavioral and operational analysis which utilizes blocks and super-blocks connected with signals as in physical systems. The modeling method incorporates an algebraicly simplified set of equations in stationary 2-axes reference frame.
