Latest Patents

Takuya Sugai holds a patent for a "Method of controlling power conversion device." This invention involves a correction-term adder that compares a maximum value max(V*) with an absolute value of a minimum value min(V*). The adder selects a signal 1−max(V*) when the maximum value is larger than the absolute value of the minimum value. Conversely, it selects a signal −1−min(V*) when the absolute value of the minimum value is larger than the maximum value. This process allows for the calculation of a correction amount α. Additionally, the correction-term adder produces a triangular-wave-shaped signal k(max(V*)+min(V*)) by multiplying a gain k by the addition signal of the maximum and minimum values. This signal is synchronized with the correction amount α, and the adder generates a correction amount β by selecting the smaller absolute value between the triangular-wave-shaped signal and the correction amount α, which is then added to the voltage command values.
