Title: Kiyoshi Aizawa: Innovator in Power Conversion Technology
Introduction
Kiyoshi Aizawa is a notable inventor based in Yokkaichi, Japan. He has made significant contributions to the field of power conversion technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and functionality of power converter apparatuses.
Latest Patents
Aizawa's latest patents include a power converter apparatus that features a control unit capable of performing cyclical control. This control unit cyclically repeats switching control that alternates operations between a third operation, a first operation, and a second operation in a specific order. The control unit executes first control, where a third switching element is switched between off, on, and off states during each first operation. Additionally, the third switching element is kept in the off state during each third operation.
Another significant patent is a DC-DC converter that incorporates a charge pump circuit for determining operation timing. This innovative design includes a bootstrap circuit unit that applies a voltage higher than that at a first connection point between switching elements during a first conversion operation. The charge-pump circuit unit steps up an input voltage and applies the resulting voltage to the drive unit, which sets the voltage of the first and second drive signals based on the applied voltages.
