Title:
SEMICONDUCTOR POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/096151
Kind Code:
A1
Abstract:
This semiconductor power conversion device has: the n (n is a natural number) number of reverse conversion devices (INVU1-INVUn), which are insulated from each other, and output voltages at three levels; and a reverse conversion device (INVUS), which has, as an input direct current voltage, a voltage (VDCS) that is a half or one third of the input direct current voltage (VDC) of the reverse conversion devices (INVU1-INVUn), and which is insulated from the reverse conversion devices (INVU1-INVUn), and outputs voltages at three levels. Then, the reverse conversion devices (INVU1-INVUn) and the reverse conversion device (INVu) are connected in series, and a voltage (VDC×n+VDCS) is outputted at a maximum.
