Latest Patents

One of Shiraishi's latest patents is a load driving device that includes a driving switching element, an interrupting part, a short-circuiting switching element, and a protecting element. This innovative device drives a load by controlling energization to it. The interrupting part is strategically placed on the energizing path to the load, ensuring it is not melted by the driving current but is melted by a larger interrupting current to effectively interrupt energization. Additionally, the short-circuiting switching element is connected in parallel with the load to apply the interrupting current to the interrupting part, while the protecting element safeguards the short-circuiting switching element.

Another notable patent is for a switching power supply that converts an input voltage to a predetermined output voltage by controlling a switching device. This power supply features a controller and a current detector. The controller manages the switching device, while the current detector monitors the electric current flowing through it. When the detected current exceeds a predetermined threshold, the controller initiates a forced-OFF action to turn off the switching device, ensuring safety and efficiency.
