1. A system comprising:
a driver circuit configured to output trigger signals;
a circuit board having a first input terminal at a first input interface and a second input terminal at a second input interface, the first input terminal and the second input terminal each connected with the driver circuit to receive the trigger signals from the driver circuit, the circuit board including a first group of conductive traces conductively coupled with the first input terminal and a second group of conductive traces conductively coupled with the second input terminal; and
power modules configured to be coupled with the circuit board, each of the power modules having first and second switches, wherein each of the first switches of each of the power modules is conductively coupled to the first input terminal by one conductive trace of the first group of conductive traces, and wherein each of the second switches of each of the power modules is conductively coupled to the second input terminal by one conductive trace of the second group of conductive traces,
wherein a first conductive trace of the first group of conductive traces and a second conductive trace of the first group of conductive traces are disposed on the circuit board to expose the first conductive trace to a first temperature and to expose the second conductive trace to a second temperature that is different from the first temperature, and wherein the first conductive trace and the second conductive trace are physically configured such that the first conductive trace has a resistance value at the first temperature and the second conductive trace has the resistance value at the second temperature, such that a first switch conductively coupled to the first input terminal via the first conductive trace and a first switch conductively coupled to the first input terminal via the second conductive trace receive trigger signals simultaneously via the first group of conductive traces, and
wherein the trigger signals to activate the first switches of each of the power modules and the trigger signals to activate the second switches of each of the power modules are received in a complimentary manner.
