1. An electrical system comprising:
a DC/DC converter including a first transistor and a second transistor, the DC/DC converter configured to receive an input voltage and supply an output voltage to a load; and
a controller electrically connected with the DC/DC converter, the controller configured to operate the first transistor and the second transistor in a set of modes,
wherein, when an electrical current drawn by the load is associated with a low electrical current, the set of modes is configured to reduce noise, vibration, and harshness (NVH) by:
operating the first transistor and the second transistor in a continuous switching mode of the set of modes when the electrical current drawn by the load exceeds a first threshold,
operating the first transistor and the second transistor in a pulse width modulation (PWM) mode of the set of modes when the electrical current drawn by the load is less than the first threshold and greater than a second threshold, and
operating the first transistor and the second transistor in a burst mode of the set of modes when the electrical current drawn by the load is less than the second threshold.
