We present a control approach for the modular multilevel converter (MMC) with series and parallel module connectivity (MMSPC) that provides natural module balancing, reduced conduction losses, and enhanced robustness afforded by the parallel mode. In conventional MMC control, the voltage of each module's storage element has to be measured or estimated to enable the controller to equalize the voltages...
A new supply modulator architecture for robust performance against the battery voltage variation is presented. The resulting modulator is an optimized power management integrated circuit (PMIC) for an envelope tracking (ET) power amplifier (PA). The basic topology of the PMIC is based on a hybrid switching amplifier combining a wideband class-AB buffered linear amplifier and a highly efficient switching-mode...
This paper describes technical solutions to be adopted by Electric Vehicles (EV) battery grid interfaces, in order to get the provision of ancillary services to the grid. The developed solution exploits an EV battery charge control approach based in a grid cooperative response to frequency and/or voltage deviations. To be effective, those cooperative actions must result from both centralized/coordinated...
