Title: Self-excitation type converter
Inventor: NOMURA JUNICHI
IPC: H02M1/12
Filed: 2003-01-29
Abstract: <P>PROBLEM TO BE SOLVED: To provide a self-excitation type converter which can perform a low cost/low loss of the converter without necessity of increasing the current capacity of a capacitor for constituting a filter circuit and without adding a damping resistor.  <P>SOLUTION: In the self-excitation type converter in which a plurality of three-phase bridge circuits are connected in parallel with each other, the filter circuit (three-phase capacitor) 74 is connected to a position where all the outputs or all the inputs of the three-phase bridge circuits 73<SB>1</SB>and 73<SB>2</SB>. If the filter circuit 74 is constituted of a plurality of filter circuits connected in parallel with each other, all the filter circuits are connected to the same position. Thus, since a uniform voltage is applied to all the filter circuits, the resonance current between the filter circuits can be suppressed. Accordingly, the increase of the current capacity of the capacitor for constituting the filter circuit, the addition of the damping resistor, etc. are not necessary.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
