Latest Patents
One of Takeuchi's latest patents is a power factor correction circuit. This innovative circuit steps up and corrects the power factor of a rectified voltage derived from an AC input voltage. It operates through an ON/OFF mechanism of a switching element and supplies a stepped-up output voltage to a DC-DC converter driven by a first pulse signal. The circuit includes a delay mechanism that generates a delay pulse signal in response to the first pulse signal, synthesizing it into a second pulse signal to drive the switching element effectively.
Another significant patent is for a switching power supply device. This device features a boost power converter that transforms a wide range of AC input voltages into a larger DC voltage. It is designed to supply this voltage to a DC-DC converter. The device incorporates a load detection circuit, an input voltage detection circuit, and a power conversion controller that adjusts the determination reference value based on the detected AC input voltage. When a light load is identified, the controller can disable the boost power converter to enhance efficiency.
