Title:
CONVERTER DEVICE INCLUDING LOW-INDUCTANCE COMMUTATION CIRCUIT
Document Type and Number:
Japanese Patent JPH07203669
Kind Code:
A
Abstract:
PURPOSE: To obtain a converter circuit device with a low inductance by arranging a branch module in a phase module, so that a commutation circuit formed by the branch module has a small circuit region. CONSTITUTION: A single-phase module 1 contains two branch modules(BM) 2.1 and 2.2. BM 2.1 contains at least one of switch modules(SM) 3. The SM 3 has at least one power semiconductor switch 7 with a related network for a free wheel 8, an electrical circuit 9, or a current-limiting circuit 10. A commutation circuit is formed by a DC middle circuit, a positive connection part 4, a negative connection part 5, and BM1.2 and 2.2. In this case, the inductance of the commutation circuit is minimized. Specifically, at least BM2.1 is arranged in parallel with a main direction 2.1 along a connection line which is extended form the positive or negative connection part to a load connection part 6. It has at the most 500 nH and generates a switch that contributes to the floating inductance of a phase module.
