Latest Patents

One of his latest patents is titled "Start-up control for multilevel dual active bridge converter." This invention describes techniques to smooth the start of a multilevel dual active bridge converter by pre-charging the capacitors without requiring additional hardware. Various phase shift angles are utilized to determine the power delivered by the converter. The techniques allow for a predefined amount of time to pre-charge the capacitors until they reach a desired voltage, after which the smooth starting of the converter is initiated. Another significant patent is "Open phase detection," which involves a transformer with a controller that assesses the currents on both the power grid side and the inverter/load side. This innovation helps in identifying open phase conditions by comparing the currents on the delta and wye sides of the transformer.
