Patent number: 7932637Abstract: A method includes operating a microsource in a grid mode in which the microsource is connected to a utility grid. The microsource is located in a microgrid and is configured to deliver a power P1 at a frequency ?1. During operation in the grid mode ?1 is a first frequency and P1 is a first power. The first frequency is an operating frequency of the utility grid. The microsource is transferred from the grid mode to an island mode, causing a frequency change such that ?1 changes to a second frequency and a power change such that P1 changes to a second power. The frequency change occurs at a first rate with respect to the power change while ?1 is less than a slope switch frequency. The frequency change occurs at a second rate with respect to the power change while ?1 is greater than the slope switch frequency.Type: GrantFiled: February 11, 2010Date of Patent: April 26, 2011Assignee: Wisconsin Alumni Research FoundationInventors: Robert H.

Patent number: 7932624Abstract: A bus bar constitutes a power line and another bus bar constitutes an earth line. The bus bars are layered in the normal direction of an insulating substrate via an insulating member. Here, the bus bar positioned at the upper side is formed by a metal member and the bus bar positioned at the lower side is formed by a wiring layer formed on the insulating substrate. Since one of the bus bars is the wiring layer fixed to the insulating substrate, it is possible to assure heat radiation of the bus bar. Thus, it is possible to make the bus bar a wiring layer having a comparatively small cross sectional area and reduce the semiconductor module size in the normal direction. By mounting the semiconductor module on the drive device for a hybrid vehicle, it is possible to reduce the vertical-direction size when mounted on the vehicle and lower the position of the center of gravity of the vehicle to improve the running stability.Type: GrantFiled: February 14, 2007Date of Patent: April 26, 2011Assignee: Toyota Jidosha Kabushiki KaishaInventor: Tadafumi Yoshida

Patent number: 7932628Abstract: A terminal state of a terminal 15 of a vehicle is enabled to be maintained for a minimum period of time even after a drop in the voltage supply. At the same time other loads are to have no effect on the holding time. A control device for controls access to a vehicle and has a voltage source, a voltage supply terminal to which a supply voltage can be applied, and a holding circuit to which the voltage source and the voltage supply terminal are connected in a common circuit point for the purpose of holding an On state for as long as the voltage at the voltage source does not fall below a predetermined value. A switching element that is connected into the circuit between the voltage supply terminal and the common circuit point serves to separate the common circuit point from the supply voltage. The holding time is thus decoupled from the VCC currents drawn by other loads.Type: GrantFiled: September 28, 2007Date of Patent: April 26, 2011Assignee: Siemens VDO Automotive AGInventors: Georg Deschermeier, Rainer Kagerbauer, Dirk Reichow
