Title: Power converter
Inventor: MOSE TADAO
IPC: H02M7/12
Filed: 1991-05-13
Abstract: PURPOSE:To prevent the scaling-up of a capacitor having a small current ripple and used for supplying reactive power at a DC terminal by installing a first arm and a second arm connecting a self-arc-extinguishing type switching element and a diode in antiparallel and a third arm connecting the self-arc-extinguishing type switching element in antiparallel. CONSTITUTION:The main circuits 3A-3C of a self-excited inverter are composed of a P side arm 7 and an N side arm 8, in which self-arc-extinguishing devices 1 and diodes 2 are connected in antiparallel, and an intermediate arm 9, in which the devices l are connected in antiparallel. Other P and N side arms 7, 8 except the intermediate arm 9, in which the devices 1 are connected in antiparallel, are constituted in the same manner as a two-level inverter. Consequently, the intermediate arm 9 connected at the intermediate potential of a power supply is replaced with the P side arm 7 and electricity is conducted, thus outputting intermediate potential to a load terminal, then operating a power converter as a three-level inverter. Accordingly, a current ripple is reduced, and a capacitor for supplying reactive power at a DC terminal cannot be scaled up.

CONSTITUTION:At least a sheet feed section on the surface of the cylindrical body 22 of a heating roller 20 is roughened by sand blasting or the like, and a layer 21 of high mold release material such as fluororesin is formed on the sheet feed section. A heater wire 23 is housed in the cylindrical body 22, and the temperature thereof is so controlled as to be optimum for fixing, according to a signal from a temperature sensor 24 kept in contact with the surface of the body 22. A pressure roller 30 is constituted of a columnar body 32 of heat resistant rubber around a rotating shaft 31, with the surface of the body 32 coated with a layer 33 of high mold release material such as fluororesin.
