Provided are a power converter for a vehicle generator-motor and a method for controlling a vehicle generator-motor, which is used for a field winding type vehicle generator-motor configured to perform control in accordance with an external operating command in which a power converter is connected to a rotating electrical machine including a field winding and an armature winding. When the generator-motor shifts from a driving state to another operating mode, a method of stopping a driving mode is switched in accordance with an operating mode to be shifted, to thereby shift the operating mode promptly without generating an unintended power generation, an excess power generation, and an excess torque fluctuation.

A field winding rotating electrical machine includes a field current detection section, a field current control section configured to calculate a duty ratio of a current supplied to the field winding based on a field current detection value, to thereby control current supply to the field winding by using a switching element, and a field current correction section configured to estimate a time point when the field current becomes 0 A based on a control state of the field current, to specify the field current detection value at the estimated time point to be a field current correction value, and to subtract the field current correction value from the field current detection value, to thereby calculate the corrected field current value. The field current control section controls the current supply based on the corrected field current value calculated by the field current correction section.

The shift control unit executes a control to cause the through speed ratio to follow the final through speed ratio by changing only the speed ratio of the variator if a shift instruction is given from the driver a plurality of times in a row when the manual mode is selected, and advances the start of a change in the speed ratio of the sub-transmission mechanism or accelerates the progression of the change of the speed ratio as compared with the case where the manual mode is not selected when the speed ratio of the variator is maximized or minimized and the through speed ratio cannot follow the final through speed ratio.

The control device detects the B-terminal voltage by a B-terminal voltage detection section. When an abnormal voltage detection section detects that a voltage value of the detected B-terminal voltage is equal to or higher than a predetermined voltage value, all switching elements of the negative pole-side arm in a power conversion section are brought into conduction by a negative pole-side arm short-circuiting section, whereas all switching elements of a positive pole-side arm are interrupted. In addition, a field current is limited to zero or to a limit value by a field current control section.

A first circuit board (1) mounted with an electronic component (16) and a second circuit board (2) are vertically connected three-dimensionally through an interconnecting board (3) wherein the terminal portion (6) of the land electrode (5) on the interconnecting board (3) is buried in the termination material (9) of the interconnecting board (3). Consequently, the chance of peeling or cracking due to peeling stress or shearing stress acting between the upper/lower circuit boards and the land electrode by high density mounting, thermal shock or falling impact can be suppressed or buffered resulting in high reliability.

A power generation control apparatus of a rotating electrical machine for a vehicle is obtained which achieves load response control in a plurality of electric power generation control modes even if a generation voltage final target value rapidly changes. The apparatus includes a power control unit 103 and a storage battery 104 connected to a rotating electrical machine 102, and a rotation speed detection part 105 for detecting a rotational speed Na. The power control unit 103 controls power generation in a first mode when the rotational speed Na during operating as a generator is less than or equal to a predetermined value, and controls power generation in a second mode when the rotational speed Na is higher than the predetermined value. The power control unit 103 includes a generation voltage command value calculation section 111 that sets generation voltage command values Vr1, Vr2 for the individual modes, respectively, so as to follow a final target value to the storage battery 104, and a generation voltage update calculation command section 110 that instructs update timing tn, an amount of increase dH and an amount of decrease dL of each generation voltage command value to the generation voltage command value calculation section 111 based on the states of the rotating electrical machine and of the storage battery.
