Current balancing circuit and method for parallel power device drive apparatus

摘要

The present invention relates to a method and apparatus for operating two power devices in a parallel operation mode of a power device used in a large current power supply device and using only one control unit to perform a balance with respect to an output current of each power device without a reactor To a current balancing circuit of a parallel power device driving apparatus.;According to the present invention, there is no need to construct a reactor at the rear end of the power element, and the two power elements can be controlled by a single controller, thereby realizing a simpler and more inexpensive current balancing circuit of the parallel power element driving apparatus It is possible to prevent the degradation of the response characteristic due to the reactor, thereby improving the performance of the application system.
