Abstract: There are provided a driver circuit, a method of driving a power switch, and a ballast circuit. For example, there is provided a driver circuit configured to receive a control signal and operate a power switch. The driver circuit includes a first switch, a second switch, and a capacitor coupled to control terminals of the first and second switches. The driver circuit further includes a first diode coupled to a first bias terminal of the driver circuit and to the capacitor. Furthermore, the driver circuit includes a second diode coupled to a second bias terminal of the driver circuit and to a terminal of the power switch.

Abstract: Controlling an energy storage system includes providing one or more constraints to an optimization problem algorithm, determining by the optimization problem algorithm a DC bus voltage value that results in an minimum total power dissipation for the plurality of power converters, calculating a respective control variable for each of the respective plurality of power converters based on the determined DC bus voltage value, and generating control processor executable instructions to implement control of each of the plurality of power converters to achieve the calculated respective control variable. A system for implementing the method and a non-transitory computer-readable medium are also disclosed.
