Patent number: 8659248Abstract: A drive device has a break circuit. The break circuit inputs phase-current values transferred from phase-current sensors mounted on an electrical path of a motor generator. A power switching element is equipped with a freewheel diode connected in parallel with each other. An inverter has pairs of the power switching elements. In each pair, the power switching element in a high voltage side and the power switching element in a low voltage side are connected in series. It is detected for the freewheel diode to be in a freewheel mode when a forward current flows in the freewheel diode. The break circuit detects the freewheel mode where the current flows in the freewheel diode in a lower arm when the phase-current value is not less than a predetermined threshold value. The break circuit detects the freewheel mode where the current flows in the freewheel diode in an upper arm when the phase-current value is not more than the threshold current value.Type: GrantFiled: December 17, 2010Date of Patent: February 25, 2014Assignee: Denso CorporationInventors: Ryotaro Miura, Tsuneo Maebara, Yusuke Shindo, Junichi Fukuta, Junichi Nagata

Patent number: 8350601Abstract: A drive unit controls the operation of a corresponding power switching element such as IGBT which forms an inverter and a converter. The drive unit controls the operation of the corresponding power switching element to supply an operation current to a motor generator. First and second switching elements in the drive unit are simultaneously turned on when an operation signal transferred from a control device is switched to a turning-on instruction operation signal. The voltage at the gate terminal of the power switching element is shifted to a divided voltage obtained by dividing a voltage of the power source by first and second resistances connected in series in the drive unit. When a mirror time period of the power switching element is elapsed, the second switching element only is turned off in order to shift the gate voltage of the power switching element to the voltage of the power source.Type: GrantFiled: December 7, 2010Date of Patent: January 8, 2013Assignee: Denso CorporationInventors: Junichi Nagata, Tsuneo Maebara

Patent number: 7548403Abstract: An overcurrent detection circuit for detecting an overcurrent condition in an output transistor connected in series with an electrical load includes a pair of transistors having input terminals connected together. The pair of transistors is interposed between a current mirror circuit and a resistor and between the current mirror circuit and a detection transistor capable of being turned on at the same time as the output transistor. When a voltage is applied to the input terminals of the pair of the transistors, output terminals of the current mirror circuit are fixed at the same potential. Thus, even when an early effect occurs in the current mirror circuit, an electric current flowing through the resistor becomes equal to that flowing through the detection transistor. The overcurrent detection circuit can accurately detect the overcurrent condition based on a voltage drop across the resistor.Type: GrantFiled: January 18, 2007Date of Patent: June 16, 2009Assignee: DENSO CORPORATIONInventors: Junichi Nagata, Masayuki Kominami
