Abstract
Systems, apparatuses, and methods are described for power conversion. In some examples, the power conversion may be done by an inverter configured to convert a direct current (DC) input to an alternating current (AC) output. The inverter may include a plurality of capacitors connected at the input of a DC/AC module. The system may include a housing configured to house the inverter. Voltage control circuitry may be configured to increase a voltage at the input of the DC/AC module inside the housing of the inverter.
