Decoupled pcb structure to parallel power transistors

An electrical-converter system, comprising:

• a printed circuit board including at least a first layer and a second layer;
• a switching node disposed on the second layer;
• a first transistor, a second transistor, a third transistor, and a fourth transistor disposed on the first layer, the first transistor and the third transistor each having a source coupled to the switching node, and the second transistor and the fourth transistor each having a drain coupled to the switching node;
• a first conduction path from the source of the first transistor, through the switching node, to the drain of the fourth transistor, the first conduction path having a first inductance;
• and
• a second conduction path from the source of the first transistor, through the switching node, to the drain of the second transistor, the second conduction path having a second inductance,
• wherein the first inductance of the first conduction path is greater than the second inductance of the second conduction path.

A method for manufacturing an electrical-converter system, the method comprising:

• providing a printed circuit board having at least a first layer and a second layer with a switching node disposed on the second layer;
• arranging a first transistor, a second transistor, a third transistor, and a fourth transistor on the first layer of the printed circuit board in proximity to the switching node;
• and
• coupling a source of the first transistor, a drain of the second transistor, a source of the third transistor, and a drain of the fourth transistor to the switching node such that a first length of a first conduction path from the source of the first transistor, through the switching node, to the drain of the fourth transistor is greater than a second length of a second conduction path from the source of the first transistor, through the switching node, to the drain of the second transistor.
