Abstract: A gate drive unit includes a charging device, a switch, and a timing module. The charging device is conductively coupled with an electrical energy source and a power switch between the electric energy source and the charging device. The switch closes to transfer electrical energy from the energy source to the charging device. The timing module is configured to close the switch to direct the electrical energy from the electrical energy source to the charging device for a designated charging time period in order to charge the charging device with the electrical energy while the power switch is in an OFF state. The timing module opens the switch to cause the electrical energy stored in the charging device to be transferred out of the charging device in the form of a trigger current that is conducted to a gate terminal of the power switch to activate the power switch to an ON state from the OFF state.

Abstract: A system and method for conditioning DC power received from hybrid DC power sources is disclosed. A power conversion circuit is coupled to a respective DC power source to selectively condition the output power generated thereby to a DC bus voltage. The power conversion circuit includes a switch arrangement and capacitors arranged to provide a charge balancing in the power conversion circuit. A controller in operable communication with the switch arrangement receives inputs on a DC bus voltage and at least one parameter related to operation of the DC power source, and determines an adjustable voltage to be output from the conversion circuit to the DC bus based on the received inputs. The controller then selectively controls operation of the switch arrangement in order to generate the determined adjustable voltage.
