Load Switching Helps Implement Hot Swaping
... inserted into the larger system, a board's hot swap controller must ensure that power at the connector is stable before being distributed to other onboard systems and commanding the board to initialize. For boards drawing little current, power can be switched onboard with digitally switched MOSFETs. ...

Power inverter
A power inverter, or inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC).The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.A power inverter can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry.Static inverters do not use moving parts in the conversion process.
