Latest Patents
Sugawara's latest patents include a motor driving method, a battery pack, and a semiconductor device. The motor driving method provides a way to variable-control a bus voltage from a battery pack. This invention utilizes a battery pack that outputs a bus voltage to a positive voltage node while using a negative voltage node as a reference. An inverter unit converts the bus voltage to AC voltage by switching according to a PWM signal, which drives a motor. The motor control unit generates the PWM signal and outputs a voltage instruction signal for instructing the bus voltage toward the battery pack. The battery pack variable-controls the number of cells coupled in parallel between the positive and negative voltage nodes to obtain the desired bus voltage.
Another notable patent is the semiconductor power module and drive system for electric motors. This invention allows for easier detection of erroneous mounting of a semiconductor power module. It includes a status signal generation unit that detects the status within the semiconductor power module and generates a status signal. Additionally, an identification information storage unit stores identification information for the semiconductor power module and outputs an identification signal. A switching unit selects between the status signal and the identification signal to output the selected signal externally.
