Latest Patents

One of Sudou's latest patents is a Single Transformer Switching Regulator. This invention comprises a single transformer with a primary winding connected to an input circuit for receiving direct-current energy and a secondary winding connected to an output circuit. A switching transistor is connected in series with the primary winding, and a high-frequency pulse generator triggers the switching transistor to interrupt the direct-current energy at a high frequency. A rectifier converts the high-frequency energy developed in the secondary winding into constant direct-current output energy. Additionally, a low voltage detector produces a signal when the direct-current energy in the input circuit falls below a specified value, allowing for backup power from a battery.

Another notable patent is a Converter, which includes a voltage transformer, a switching transistor, a resistor, a control transistor, and a control circuit. The voltage transformer has a primary winding, a secondary winding, and a control winding. The switching transistor is connected in series with the primary winding, while the resistor connects the switching transistor to one terminal of an input power source. The control transistor is linked to the connection point between the resistor and the switching transistor, and the control circuit manages the control transistor based on a control voltage extracted from the control winding.
