Latest Patents

Masuya holds a patent for a Switching Power Supply Unit. This invention features a control function formula that establishes a relationship between an output voltage signal (Vo) and an output differential value, utilizing a negative linear function defined within a calculation means. The calculation means samples an input voltage signal, an output voltage signal, and an output differential signal at time instants synchronized with the switching cycle of a main switching element. It calculates the subsequent ON and OFF durations of the main switching elements to satisfy the control function formula. Additionally, a drive pulse generation means produces a drive pulse that turns the main switching element on and off based on the determined ON and OFF durations. The output differential signal is generated by a capacitor current detection means or an observer device that detects the current of a smoothing capacitor.
