Abstract: An apparatus includes an active bridge section with input terminals that receive power from a constant current source where the active bridge section operates at a fixed switching frequency. The apparatus includes a resonant section with a resonant inductor, a transformer and a resonant capacitor. The inductor is connected in series with a primary winding and the capacitor is connected in parallel with a secondary winding of the transformer. The resonant section is connected to an output of the active bridge section. The apparatus includes an output rectifier section that receives power from the resonant section and includes output terminals for connection to a load, and includes a controller that regulates output voltage to the load where the controller regulates output voltage to the load by controlling switching of the active bridge section. The fixed switching frequency of the active bridge section matches a resonant frequency of the resonant section.

Abstract: For battery control, an apparatus includes a shared bus and a plurality of isolated direct current (DC) to DC bypass converters. Each bypass converter is associated with one battery unit. Inputs of each bypass converter are in parallel electrical communication with the associated battery unit. Outputs of each bypass converter are in parallel electrical communication with the shared bus. Each bypass converter estimates a battery state for each battery unit and controls the battery state to a reference state.

Abstract: An apparatus includes a battery state module that determines a battery state of each of a plurality of battery cells forming a battery unit. A battery state includes a health of the battery cell. A battery state of a battery cell differs from a battery state of other battery cells of the battery unit. Each battery cell is connected to a shared bus through a bypass converter that provides power from the battery cell to the shared bus. A charge/discharge modification module determines, based on battery state, an amount to vary a charging characteristic for each battery cell compared to a reference charging characteristic. Each charging characteristic varies as a function of a reference state. A charge/discharge module adjusts charging/discharging of a battery cell of the battery unit based on the charging characteristic of the battery cell.
