With a total of 2 patents, Okada's work showcases his innovative approach to solving complex engineering challenges.
Latest Patents
One of Okada's latest patents is titled "Sampling external voltage which may exceed integrated circuit maximum voltage rating." This invention involves an LED driver arrangement where a low voltage integrated circuit (IC) samples the voltage at a terminal of each electronically controlled switch. These switches control multiple LED strings powered by a single source, which may exceed the voltage rating of the IC. The design ensures that the IC only sees a voltage lower than its maximum rating when the associated LED string is illuminated.
Another significant patent is the "Fine tuned multiple output converter." This invention applies a secondary side voltage regulation scheme to a multiple output flyback converter. It selects the output with the highest error voltage to control the primary switch, while regulating the remaining outputs by varying the current flow duration. This innovative approach utilizes a single N channel MOSFET for each output, enhancing the efficiency of the converter.
