Latest Patents
One of Sawada's latest patents is a gate drive circuit. This circuit features a capacitor and a gate drive voltage source connected in series with a gate terminal of a voltage-driven switching device. The gate drive source voltage provides a gate drive voltage that exceeds the sum of the voltage applied to the gate-source parasitic capacitance of the switching device when it is in a steady ON state. Additionally, it accounts for any voltage applied by circuit components interposed between the gate drive voltage source and the gate terminal of the switching device. Notably, the capacitor is the sole circuit component directly connected to the gate terminal, eliminating the need for other components such as resistors.
Another significant patent by Sawada is related to a power module and output circuit. This innovation includes a first high-side main-circuit MOSFET and a second low-side main-circuit MOSFET connected in series. The series circuit of the MOSFETs is connected in parallel to a power source. Furthermore, a first short-circuit MOSFET is connected between the gate and the source of the first main-circuit MOSFET, while a second short-circuit MOSFET is connected between the gate and the source of the second main-circuit MOSFET.
