Latest Patents
One of Terasawa's latest inventions is a battery voltage detector. This device features voltage-dividing resistors arranged in parallel with a first DC power supply. It includes a first switch that connects to both a first and a second resistor, along with a control terminal. A second switch is responsible for switching the supply of power voltage from a second DC power supply. The voltage comparator within the device has first and second input terminals, with a reference power supply connected to the first input terminal to output a reference voltage. The control terminal of the first switch is linked to the positive voltage side of the second DC power supply, allowing voltage to be applied to the resistors when power is supplied.
Another notable invention is an interleaved DC-DC converter, which comprises a control circuit and multiple boost converters connected in parallel. This converter includes an output voltage detection circuit that compares a detected voltage with a reference voltage, generating an error signal. It also features PWM generators that drive the switching elements of the converters, current error amplifiers for feedback, and a differential detector that monitors feedback signals. The latch circuit halts all switching operations when a significant difference is detected.
