Latest Patents

Morimoto's latest patents include a power supply circuit and a power supply device. The power supply circuit is of a step-down type, designed to generate an output voltage at a predetermined level from an alternating current (AC) voltage. This circuit features a rectifier circuit for rectifying the AC voltage, a first line connected to the rectifier, a second line on the ground side, a switch between the two lines, and a control circuit that regulates the switch to maintain the output voltage at the desired level. Notably, this power supply circuit does not include an inductor between the first line and the rectifier circuit.

Another significant patent is for a semiconductor drive device and power conversion apparatus. This invention utilizes first and second current detection resistors connected in series to detect the main current of a switching element. A single-fault detection circuit divides the voltage detected from the main current using first to third resistors. Two comparators are employed to compare voltages at various points, ensuring that if one of the current detection resistors is short-circuited, the system can still maintain the same output voltage as before the fault occurred.
