Latest Patents

One of Issei Toda's latest patents is an electric circuit device designed to protect loads connected to a connector terminal during short-circuit conditions. This innovative device ensures that when a voltage at the cathode of a diode reaches or exceeds the output voltage of a power source circuit due to a short circuit, the output voltage of an amplifier adjusts accordingly. This adjustment allows the switching element to enter an open state, effectively blocking current flow to the negative terminal and protecting the load from overcurrent.

Another notable patent is a power conversion device that addresses overvoltage issues in vehicles during non-operation states. This device is connected to a three-phase motor and includes an inverter circuit, a gate drive substrate, and a motor control substrate. When the vehicle is not in operation and a regenerative voltage exceeds a predetermined threshold, the power supply circuit activates the control circuit. This circuit then outputs gate control signals to manage regenerative energy between the motor and inverter circuit, ensuring efficient energy consumption.
