MOSFET CIRCUIT COMPRISING A SWITCH OF SWITCHING-TYPE CELL VOLTAGE BALANCING CIRCUIT HAVING SERIES-PARALLEL CIRCUIT AND DRIVING CIRCUIT THEREOF

摘要

There is provided an equalizing circuit for a storage cell voltage having a smaller number of elements and a simpler circuit configuration than the prior art. The respective parallel circuits formed in any of the connection states realized by switch switching in which the storage cells to be mutually charged and discharged to be connected in parallel to each other are connected in parallel to each other, By arranging the field effect transistor so as to have the transistor and the field effect transistor arranged so as not to block the other polarity current in the parallel circuit, voltage equalization operation by a small number of transistors is enabled.
