1. A system comprising:
an inverter configured to convert DC power from a battery to AC power to drive a motor, wherein the inverter includes:
a first decoupling capacitor configured to be connected to a positive connection of the battery and a negative connection of the battery; and
a first power module including:
one or more point-of-use controllers configured to operate in an electromagnetic field with a value greater than 10A or greater than 100V,
a first upper phase switch configured to control a first upper phase flow of current between the positive connection of the battery and a first phase connection of the motor, and
a first lower phase switch configured to control a first lower phase flow of current between the negative connection of the battery and the first phase connection of the motor,
wherein terminals of the first decoupling capacitor are connected substantially adjacent to a drain terminal of the first upper phase switch and a source terminal of the first lower phase switch.
