Latest Patents

Kikuchi's latest patents include a Switching Power Supply Circuit and a Noise Filter. The Switching Power Supply Circuit features a signal generation circuit that utilizes a capacitor charged and discharged by a current proportional to an input voltage. It includes a switch that controls the charging and discharging of the capacitor based on an output signal from a comparator. This comparator compares a feedback voltage according to the output voltage with a predetermined first reference voltage. Additionally, a reference voltage generation unit generates a second reference voltage by adding an offset voltage proportional to the input voltage to an output proportional voltage. The circuit also includes a comparator that generates an ON-time signal based on the terminal voltage of the capacitor and the second reference voltage.

The Noise Filter is designed to suppress common mode voltage generated in cables connected to an electric power converter. It consists of detecting capacitors that detect the common mode voltage, an operational amplifier that inputs the detected voltage, and an emitter follower circuit that connects to the operational amplifier. Furthermore, a transformer applies a compensating voltage to each cable in opposite phase, enhancing the filter's effectiveness.
