Abstract
A power supply that includes a battery pack, a sensor configured to sense an electrical characteristic of the battery pack, a reconfigurable voltage boost circuit configured to connect to an inverter, and a controller. The reconfigurable voltage boost circuit is configured to switch between a voltage doubler configuration and a voltage tripler configuration in response to a switching control signal based on the electrical characteristic of the battery pack. The controller is connected to the battery pack, the sensor, and the reconfigurable voltage boost circuit. The controller is configured to obtain the electrical characteristic of the battery pack from the sensor, compare the electrical characteristic to a switching threshold, and transmit the switching control signal to the reconfigurable voltage boost circuit based on the comparison of the electrical characteristic and the switching threshold to switch between the voltage doubler configuration and the voltage tripler configuration.
