Title: Akira Hayakawa: Innovator in Switching Power-Supply Technology
Introduction
Akira Hayakawa is a prominent inventor based in Niiza, Japan. He has made significant contributions to the field of power supply technology, holding a total of 9 patents. His work focuses on enhancing the efficiency and functionality of switching power-supply devices.
Latest Patents
One of Hayakawa's latest patents is for a switching power-supply with switching frequency correction. This innovative device applies a DC voltage to a primary winding of a transformer and performs a switching operation of a switching element connected to the primary winding. It generates and outputs an output voltage to a load. The device includes an error amplifier that compares the output voltage with a reference voltage, sending an error voltage as feedback to the primary side. Additionally, it features a frequency generation circuit that generates a switching frequency based on the feedback signal, an off timing determination circuit that determines when the switching element should turn off, and a frequency correction circuit that adjusts the switching frequency according to the on-duty of the switching element.
Another notable patent is for an integrated circuit and switching power-supply device. This device consists of an inductor and a switching element connected in series. It includes a control circuit that manages the on and off states of the switching element and performs output voltage control in various modes, including continuous and discontinuous modes. A continuous mode detection circuit is also present, which detects when output voltage control is being performed in continuous mode based on the current flowing through the switching element.
