Document Type and Number:
Japanese Patent JP2004537942
Kind Code:
A
Abstract:
A series power switch bridge having the ability of automatic voltage-sharing, which belongs to the field of electric controlling equipments. It consists of a power switch bridge and a dynamic-static voltage-sharing absorption circuit (DRwC) bridge. The very power switch bridge is constituted of several power switches in series. The number of DRwC circuits in the dynamic-static voltage-sharing absorption circuit bridge is correspondence with the number of power switches. The positive terminal and the negative terminal of every DRwC circuit and the corresponding power switch are connected respectively. The very DRwC circuit consists of a diode (D), a capacitance (C) and a voltage regulator (Rw), and the diode (D) is connected in series with the circuit of the voltage regulator (Rw) and the capacitance (C) which are in parallel. The serial DRwC circuit can deal the serial power switch with static voltage-sharing, dynamic voltage-sharing and absorption of the bounce voltage. In this way, the work capability and the accuracy of voltage-stabilizing of the power switch series bridge can be improved greatly.
