Latest Patents

One of his latest patents is titled "Digital like short circuit to ground protection for DC-DC converter." This invention describes an adaptive method to protect a DC to DC buck converter from destruction in the event of a short circuit to ground at the output. The short circuit protection method is small and inexpensive, utilizing very low current, which allows the buck converter to remain active and protected. It self-regulates below an acceptable maximum peak current. The inductor current is sensed in the current-mode loop circuitry, and an over-current comparator is employed. A masking interval generator is necessary to mask false over-current triggers caused by converter switching-induced glitches. Simple logic is used to detect if the current-limit comparator indicates over-current at the end of the masking interval, implementing over-current pulse-skipping on genuine over-current detection.

Another significant patent is "Synchronous rectifier for buck converter without the need for a comparator." This invention involves a switch mode power supply that functions in both continuous and discontinuous current modes. It employs a zero crossing control circuit to determine the polarity of an inductor current. From this polarity, the operational state of a switching section of the switch mode power supply is controlled, ensuring that the inductor current approaches zero amperes at the end of each demagnetization phase of operation.
