摘要： A semiconductor device of a three-level inverter circuit with a reduced number of power supplies for driving IGBTs. The semiconductor device includes a series-connected circuit of IGBTs between P and N of a DC power supply and an AC switch element that is connected between a series connection point of the series-connected circuit and a neutral point of the DC power supply. The series-connected circuit and the AC switch element are integrated into one module. The AC switch element is formed by connecting a collector of a first IGBT to which a diode is connected in reverse parallel and a collector of a second IGBT to which a diode is connected in reverse parallel, and an intermediate terminal is provided at a connection point between the collectors.

摘要： An image signal encoding system wherein image signal is directly taken in through video camera, changed to digital data, broken down into PDI basic patterns, and then converted into NAPLPS code automatically. The taken-in image signal is divided into a plurality of areas and the information amount of the image signal is reduced for adequate encoding after taking in the image signal. Usually "POLYGON" command is used as the NAPLPS code.
