Latest Patents

One of his latest patents is a control method for a direct power converter. This invention allows for the direct conversion of AC voltage into an AC voltage of any desired magnitude and frequency. It operates by turning bidirectional switches ON and OFF without the need for an energy buffer. The design limits the peak values of output phase voltage command values, ensuring that the amplitude of the output line voltage does not exceed 0.866 times the amplitude of the supply line voltages. For instance, the peak-value limit is set so that the maximum output phase voltage command values are at most 0.75 times the maximum supply phase voltages, while the minimum values are at least 0.75 times the minimum supply voltages. This innovative control method eliminates the need for an expensive dedicated motor, thereby reducing the overall cost of the control apparatus.

Another significant patent is for a motor driving apparatus that drives a motor using an AC/AC direct converter, such as a matrix converter. This apparatus includes a current detecting section to monitor motor currents, a comparing section to check if these currents exceed a restriction level, an induction voltage calculating section, a switching section, and a PWM pattern generating section. When the comparing section detects that the motor current detection values have surpassed the restriction level, the switching section supplies the calculated induction voltages to the converter as output voltage instruction values.
