Latest Patents

One of Miki's latest patents is a gate drive circuit that applies a first voltage between a gate and a source of a switching element to turn it on. After the transference of drain current, the circuit interrupts the first voltage and applies a second voltage that is lower but higher than a mirror voltage of the switching element. This innovative approach ensures that when no short-circuit current is flowing, a third voltage higher than the second voltage is applied. Another notable patent is for a power converting device that includes upper-arm and lower-arm gate drive circuits. These circuits drive semiconductor switching elements and feature time point detection circuits that monitor voltage crossings at reference levels. The device's controller calculates inverter output voltage changes and generates PWM command pulses accordingly.
