The present invention relates to an integrated magnetic component comprising a magnetically permeable core. The magnetically permeable core comprises a base member extending in a horizontal plane and first, second, third and fourth legs protruding substantially perpendicularly from the base member. First, second, third and fourth output inductor windings are wound around the first, second, third and fourth legs, respectively. A first input conductor of the integrated magnetic component has a first conductor axis and extends in-between the first, second, third and fourth legs to induce a first magnetic flux through a first flux path of the magnetically permeable core. A second input conductor of the integrated magnetic component has a second coil axis extending substantially perpendicularly to the first conductor axis to induce a second magnetic flux through a second flux path of the magnetically permeable core extending substantially orthogonally to the first flux path. Another aspect of the invention relates to a multiple-input isolated power converter comprising the integrated magnetic component.

The invention provides an anti-pinch control method for a vehicle open-close body. In method, a self-study initializing step of the open-close body is finished first and then the anti-pinch control of the open-close body is realized. The anti-pinch control method comprises the following steps of: judging the area where the open-close body is positioned by acquiring a current position signal of the open-close body; acquiring a rotating speed value n and a voltage value U of a current motor, and obtaining the current load torque value T of the motor according to the formula 3:n=aU-kT-A; comparing an anti-pinch torque threshold Tp and the load torque value; if the T is greater than the Tp, controlling the motor to rotate reversely according to the judgment results of the area where the open-close body is positioned currently and the stroke position of the area; and otherwise, continuing to perform the current operation. In the anti-pinch method, the error of anti-pinch force is only related to the rotating speed droop constant of an actual motor, so that the effect of reducing variable number to reduce the error is achieved; the requirement on motor consistency is low; and the control cost is reduced.

The invention discloses a power plant level automatic power generation control system applied load optimizing and distributing method. The method is carried out through the following steps: pre-classifying a plurality of sub-clusters of generator sets according the properties of the generator sets of the power plant; optimizing and distributing load to the plurality of sub-clusters of generator sets according to the principle of using the least amount of coals; attaining the best load state space of each generator set in each sub-cluster of the generator sets within an allowed load and storing best load state space in a database of a system; performing load distribution according to a speed regulation priority method or a coal consumption optimizing method so as to check the best load state space of the sub-clusters of generator sets and attaining the best load of all generator sets in the power plant with the attained best load of all machines transmitted to an automatic control system through a monitoring apparatus of a plant level AGC system. The invention further provides a system corresponding the method. According to the invention, the method is capable of effectively shortening the calculation and distribution time for load when a power plant comprises a great number of generator sets with vast type difference so as to fulfill the requirement of safety control to a power grid and to improve the authenticity and the accuracy of an optimization result.
