Abstract:
A power converter comprising:a semiconductor circuit including a first semiconductor device and a second semiconductor device each having a main terminal and a control terminal, and electrically connected to each other; a main circuit wiring including a plurality of tabular conductors arranged at least partially in superposed relation to each other, a main circuit current of said semiconductor circuit flowing in said main circuit wiring; a first control signal line for supplying a first control signal to said control terminal of said first semiconductor switching device; and a second control signal line for supplying a second control signal to said control terminal of said second semiconductor switching device; wherein the sum of the length of that portion of each of said first control signal line and said second control signal line which is opposite to an area of said main circuit wiring where said main circuit current flows and where said plurality of said tabular conductors are in superposed relation to each other, the length of that portion of each of said first control signal line and said second control signal line in opposite relation to an area of said main circuit wiring where said main circuit current does not flow, and the length of that portion of each of said first control signal line and said second control signal line which is located outside an end of said main circuit wiring, is substantially equal to the total wiring length of each of said first control signal line and said second control signal line.
