Latest Patents
Azuhata's latest patents include a power supply device and an overcurrent protective device. The power supply device features a first resistor and a second resistor connected in series between an output terminal and a reference potential. It includes a power converter that supplies a first voltage to the output terminal and controls this voltage to maintain a predetermined value at a reference point. Additionally, it has a protective current output circuit that outputs a protective current based on the output current and a limit current. The control circuit draws in a current from the reference point, subtracting the protective current from a set current.
Another significant patent is a signal amplifier that comprises a pulse width modulator, a level shifter, and a power amplifier. The pulse width modulator is driven by both positive and negative power supplies, with its reference voltage set to ground. The power amplifier operates on a positive power supply, with its reference voltage set to a midpoint between the positive supply and ground. The level shifter adjusts the voltage level of a first PWM signal to match the voltage level of a second PWM signal.
