Latest Patents

One of his latest patents is a "Backup power supply system with a null transfer time." This innovative system supplies power from a primary AC source under normal conditions. When the primary source fails, the system seamlessly switches to a secondary AC source without any transfer time. This design ensures that there is no circulating current generated, allowing for a continuous power supply.

Another significant patent is the "Control method for parallel-connected power converters." This method includes a control circuit that utilizes both voltage feedback and current feed-forward circuits. The voltage feedback circuit maintains a constant output voltage with low total harmonic distortion. By adjusting the gain of the waveform control circuit, the current distribution among parallel-connected converters is regulated. This innovation helps suppress circulating currents and prevents high-frequency oscillations.
