  • Publication number: 20240372476
    Abstract: A bidirectional power supply includes an alternating current (AC) port as a source in a first mode and as a load in a second mode and a line-frequency rectifier/inverter to function as a rectifier in the first mode and a set of switches to function as an inverter in the second mode. A bidirectional resonant converter is coupled to a direct current (DC) port with primary-side switches and secondary-side switches respectively arranged on a primary and secondary side of a transformer. A controller controls the primary-side switches and the secondary-side switches by controlling switching frequency based on a determined value while setting time delay between control of the primary-side and the secondary-side switches to be a predefined time delay or by controlling the time delay between control of the primary-side and the secondary-side switches based on a determined value while setting the switching frequency to be a predefined switching frequency.

  • Patent number: 12132425
    Abstract: A motor drive system includes an electric motor, a drive circuit and a control unit. The drive circuit provides a driving current to the electric motor. A current command generator of the control unit generates a current command according to a torque command and a motor operating information. The driving current is converted into a d-axis current and/or a q-axis current by the control unit. Consequently, the driving current is close to the d-axis current command and/or the q-axis current command corresponding to the current command. If a value of the torque command is positive, the current command generator generates the corresponding current command according to a MTPA lookup table. If the value of the torque command is negative, the current command generator generates the corresponding current command according to a zero recycle lookup table.

  • Patent number: 12132348
    Abstract: A dual power switching system includes a first STS, a second STS, an inductive device, and a controller. The first STS is electrically coupled to a main power source, and the second STS is electrically coupled to a backup power source. When detecting that the main power source is abnormal, the controller detects a residual magnetic flux of the inductive device and calculates a magnetic flux difference between the predicted magnetic flux and the residual magnetic flux. When determining that an absolute value of the magnetic flux difference is less than or equal to a magnetic flux deviation value, the controller determines whether the output power meets a forced commutation condition. When determining that the output power meets the forced commutation condition, the controller turns on the second STS so that the first STS is forcibly turned off by the backup power source through the second STS.
