1. An apparatus comprising:
converter circuitry comprising an inductor and configured to convert an input power to an output power, wherein the converter circuitry is configured to:
transition, in a first time period, from a first state to a second state, and
transition, in a second time period, from the second state to the first state, wherein the first state is during a positive half cycle of an alternating current (AC) power source associated with the converter circuitry, and the second state is during a negative half cycle of the AC power source associated with the converter circuitry; and
dampening circuitry comprising:
first energy dissipation circuitry; and
second energy dissipation circuitry,
wherein:
the first energy dissipation circuitry is connected to a terminal of the converter circuitry and configured to discharge a first voltage associated with common mode switching within the first time period,
the second energy dissipation circuitry is connected to the terminal of the converter circuitry and configured to discharge a second voltage associated with common mode switching within the second time period, and
the converter circuitry is further configured to:
connect, during the positive half cycle, a negative terminal of the AC power source to ground potential;
connect, during the negative half cycle, the negative terminal of the AC power source to the terminal of the inductor; and
connect, during the negative half cycle, a negative terminal of the AC power source to ground potential.
