Latest Patents
Sakakibara's latest inventions include the following patents:
1. **Power Supply Control Apparatus**: This invention governs the power supply from a direct current (DC) power source to a load by switching a power supply field-effect transistor (FET) on or off. It features a current adjustment circuit that fine-tunes the current through a resistor circuit based on the voltage between the drain and source of the power supply FET, divided by the resistance value of the resistor. Additionally, a drive circuit is integrated to turn off the FET when the voltage across a detection resistor surpasses a predetermined threshold, accounting for variations in ambient temperature affecting the FET's on-resistance value and the resistor circuit's resistance.
2. **Power Supply Control Device**: This control device manages power by operating two semiconductor switches along a current path. It involves diodes strategically connected between the drain and source of each switch, ensuring that if current flows despite the switches being instructed to turn off by a microcomputer, a drive circuit will reactivate the first semiconductor switch.
