Problems solved by technology

[0004] However, in the motor drive device disclosed in the aforementioned Japanese Patent Application Laid-Open No. 4-295202, the drive of the induction motors MA and MB must be stopped in the recharging mode.
In addition, during the drive control of the induction motors MA and MB (in the drive mode), the control in the recharge mode cannot be performed.
[0005] Furthermore, in the above-mentioned gazette, although it is disclosed that the battery charging with a power factor of 1 is performed from a single-phase power source in order to realize battery charging efficiently, a higher precision control is required to realize more efficient battery charging or to charge the battery to an external device. powered by

Embodiment approach 1

[0067] FIG. 1 is an overall block diagram of a hybrid vehicle shown as an example of the vehicle according to Embodiment 1 of the present invention. Referring to FIG. 1 , this hybrid vehicle 100 has an engine 4 , motor generators MG1 , MG2 , a power distribution mechanism 3 and wheels 2 . In addition, hybrid vehicle 100 also has power storage device B, inverters 20 , 30 , and electronic control unit (ECU) 60 .

[0068] Furthermore, the hybrid vehicle 100 further includes: capacitor C1, power line PL1, ground line SL, U-phase lines UL1, UL2, V-phase lines VL1, VL2, W-phase lines WL1, WL2, voltage sensor 72, and current sensors 82, 84 . In addition, hybrid vehicle 100 also has power lines NL1 , NL2 , connector 50 , capacitor C2 , voltage sensor 74 , and current sensor 86 .

[0069] This hybrid vehicle 100 runs using engine 4 and motor generator MG2 as power sources. Power split mechanism 3 is combined with engine 4 and motor generators MG1, MG2 to distribute power among them....

Embodiment approach 2

[0129] In the first embodiment, only the inverter 20 (or 30 ) performs the PWM operation based on the zero-phase voltage command E0 , but in the second embodiment, both the inverters 20 and 30 perform the PWM operation.

[0130] The second embodiment differs from the first embodiment in the configuration of the inverter control unit, and the other configurations are the same as those in the first embodiment.

[0131] Figure 15 is a specific functional block diagram of the inverter control unit in the second embodiment. refer to Figure 15 , the converter control section 64A in the Figure 4 Inverter control unit 64 in Embodiment 1 shown has multiplication units 126 and 128 and subtraction unit 130 in addition to the configuration.

[0132] The multiplication unit 126 multiplies the zero-phase voltage command E0 from the current control unit 118 by 1 / 2, and outputs the calculation result to the addition unit 120 . Next, the adder 120 adds the output from the multiplier 126...

Embodiment approach 3

[0154] In order for the control quantity to track the target input without a steady deviation, it is necessary to include a generation model of the target input in the closed loop of the control system (internal model principle). Therefore, the third embodiment shows a configuration in which a model (internal model) of the current command IR is included in the closed loop of the current control system by utilizing the fact that the current command IR is a sine wave function.

[0155] Embodiment 3 is different from Embodiment 1 or 2 in the configuration of the current control unit in the inverter control unit, and the other configurations are the same as Embodiment 1 or 2.

[0156] Figure 19 It is a control block diagram showing the configuration of the current control unit in the third embodiment. refer to Figure 19 , the current control unit 118A includes a PI control unit 202 , an internal model compensation unit 204 , and an addition unit 206 .

[0157] PI control unit...

Abstract

An ECU (60) detects an effective value and phase of a voltage from a commercial power supply (90), based on a voltage (VAC) from a voltage sensor (74). Further, ECU (60) generates a command current (IR), which is a command value of current (IAC) caused to flow through power lines (NL1, NL2) and in-phase with the voltage of the commercial power supply (90), based on the detected effective value and the phase and on a charge / discharge power command value (PR) for a power storage device (B). Then, ECU (60) controls zero-phase voltage of inverters (20, 30) based on the generated command current (IR).

Description

technical field [0001] The present invention relates to a power control device and a vehicle having the power control device, and more particularly to a power control device for receiving and supplying electric power between a commercial power source and a power storage device mounted on the vehicle, and a vehicle having the same. Background technique [0002] Japanese Patent Application Laid-Open No. 4-295202 discloses a motor drive device capable of receiving and supplying electric power between an AC power supply outside a vehicle and a vehicle-mounted DC power supply. This motor drive device includes a battery, inverters (inverters) IA, IB, induction motors MA, MB, and a control unit. The induction motors MA and MB each have windings CA and CB connected in a star connection (Y connection). The neutral points NA, NB of the windings CA, CB are connected to input / output ports via an EMI filter. Inverters IA, IB are provided corresponding to induction motors MA, MB, respec...
