摘要： A flying capacitor converter comprising a protection circuit includes at least two cells, each having a capacitor having a first and second DC sides, a first switch connected to the first DC side and to a capacitor of a following cell or an output circuit, and a second switch connected to the second DC side and to the capacitor of the following cell or the output circuit. During a nominal non-fault operation of the flying capacitor converter, only one of the first and second switches is in a conducting state, and during a fault operation where the first switch has a short circuit failure and the second switch has a conducting state, the protection circuit is configured to keep the second switch switched-on.

摘要： A semiconductor unit is arranged between a motor and an inverter circuit that controls the motor. The semiconductor unit includes a transistor and a controller. The transistor is arranged between the inverter circuit and a positive electrode of a battery that supplies power to the inverter circuit, and controls supplying of power from the battery to the inverter circuit. The controller is connected to a control terminal of the transistor, and controls a control voltage that is a voltage applied to the control terminal. When power starts to be supplied from the battery to the inverter circuit, the controller controls the control voltage to intermittently operate the transistor and also decreases the control voltage, which is applied to the control terminal of the transistor, to be lower than the control voltage at which the transistor is fully activated.

摘要： Signaling open drain read back for functional safety (FUSA) applications in point of load (POL) integrated circuit. Example embodiments include methods of operating a point of load (POL) device, including: supplying power to a load via a power terminal; selectively conducting, by a field-effect transistor (FET), a current between a signal output terminal of the POL power supply device and a ground terminal of the POL power supply device to drive the signal output terminal to a low-voltage state, thereby communicating a signal; and detecting, by a monitoring circuit in the POL power supply, a status of the signal output terminal to determine whether an external device is communicating the signal on a shared communications line connected to the signal output terminal.

摘要： A failure detection circuit for a power switch transistor in a power switching converter is provided that compares a drive voltage for driving a gate of the power switch transistor to a plurality of thresholds. Based upon when the drive voltage crosses each threshold in the plurality of thresholds, a logic circuit determines whether a fault condition exists for the power switch transistor.

摘要： A method of setting a synchronous rectifier on-time value includes determining that a time interval has occurred, receiving a number of triangular current mode (TCM) pulses measured during the time interval, and determining a pulse comparison value equal to a number of switching period pulses during the time interval minus the number of TCM pulses during the time interval. The method also includes increasing the synchronous rectifier on-time if the pulse comparison value is greater than or equal to a threshold and decreasing the synchronous rectifier on-time if the pulse comparison value is less than the threshold.

摘要： Isolated direct DC/DC converter topology structure for fuel cell system includes: Boost converter topology structure and bidirectional full-bridge converter topology structure connected in sequence. Input of the Boost converter topology structure is connected to fuel cell, and output of the Boost converter topology structure is connected to other key components of the fuel cell system and input of the bidirectional full-bridge converter topology structure. Output of the bidirectional full-bridge converter topology structure is connected to power cell. Usage of the Boost converter topology structure and usage of the bidirectional full-bridge converter topology structure change under different operating states of the fuel cell system. Based on insulation performance and high efficiency of the fuel cell system, the usage of the Boost converter topology structure and the usage of the bidirectional full-bridge converter topology structure change. Low efficiency caused by DC/DC converter with single isolated topology structure is effectively overcome.

摘要： An onboard control apparatus includes a duty ratio control unit, a current control unit, and a switching unit. The duty ratio control unit performs duty ratio control so as to turn a switch on and off at a set duty ratio. The current control unit performs current control so as to change the current to be supplied to the resistor portion while continuously supplying the current to the resistor portion. The switching unit switches, when a switching condition is established while the duty ratio control unit is performing the duty ratio control, to the current control by the current control unit.
