A generator(50) includes a rotor winding and a stator winding and is rotated by the rotation force from the engine to generate a specific power. The generator supplies the power which is induced in the stator winding to the motor. A charging unit(80) charges an incoming power and discharges the power when required. An inverter for the generator(70) supplies the power which is induced in the rotor winding of the generator to the charging unit. A gear(30) mechanically couples the wheels, the motor, and the generator with one another.

본 발명은 하이브리드 자동차의 전기 동력 장치에 관한 것이며, 상세하게는 발전기와 모터를 구비한 하이브리드 자동차에서 모터용 인버터를 사용하지 않고도 모터 제어가 가능하도록 한 것이다.The present invention relates to an electric power unit of a hybrid vehicle, and more particularly, to enable motor control without using an inverter for a motor in a hybrid vehicle having a generator and a motor.

일반적으로, 급속한 산업화와 소득 수준의 증대로 우리나라의 자동차 보유 대수는 기하급수적으로 증가하고 있는 추세에 있다. 따라서, 교통문제와 자동차 배 기가스로 인한 대기 오염이 심각하게 대두되고 있음에 따라 자동차 배기가스를 저감시키기 위한 많은 방법들이 연구되고 있다. 예로서, 미국의 캘리포니아주의 경우, 전기 자동차의 판매를 법적으로 의무화하였다.In general, the number of cars owned in Korea is increasing exponentially due to the rapid industrialization and the increase of income level. Therefore, as the air pollution caused by traffic problems and automobile exhaust gas is seriously emerging, many methods for reducing automobile exhaust gas have been studied. For example, in the US state of California, the sale of electric vehicles is required by law.

그러나 전기 자동차는 에너지 밀도가 내연기관에 비해 매우 낮기 때문에 자동차로서의 성능과 기능에는 한계가 있다. 따라서 전기 자동차의 핵심 역할을 하는 배터리의 성능을 개선시키기 위한 신기술이 개발되고 있으나 아직 완전하지 못한 상태이고, 또한 배터리를 충전시키는 충전소의 설치에 많은 재원이 필요하는 등등의 현실적인 상용화에 많은 어려움이 있었다.However, electric vehicles have a very low energy density compared to internal combustion engines, which limits their performance and function. Therefore, new technologies are being developed to improve the performance of batteries, which play a key role in electric vehicles, but there are many difficulties in the practical commercialization, which is not yet complete, and requires a lot of resources to install the charging station to charge the batteries. .

상기한 바에 따른 대체 방안으로 엔진과 전기계통을 동시에 두고 베터리의 의존성을 크게 줄인 하이브리드 자동차가 출현하였다.As an alternative as described above, a hybrid vehicle has appeared which greatly reduces the dependence of the battery by simultaneously placing the engine and the electric system.

하이브리드 자동차의 동작 원리는 다른 2종류 이상의 구동원을 조합해서 동작시키는 시스템으로서, 차량의 성능을 향상시키고 현재의 내연 기관에 비해 배기가스가 현저히 줄어들어 대기오염을 줄이는 효과를 제공한다.The operating principle of the hybrid vehicle is a system that operates a combination of two or more different driving sources, which improves the performance of the vehicle and significantly reduces the exhaust gas compared to current internal combustion engines, thereby reducing air pollution.

이러한 하이브리드 자동차의 전기 동력 장치를 도 3을 참조하여 살펴보면, 바퀴(1), 엔진(2), 모터(4)와 발전기(5)들은 기어(3)를 통해서 기계적으로 연결되고, 모터용 인버터(6)와 발전기용 인버터(7)는 각각 모터(4)와 발전기(5)를 구동한다.Looking at the electric power unit of such a hybrid vehicle with reference to Figure 3, the wheel (1), the engine (2), the motor (4) and the generator (5) are mechanically connected via a gear (3), the motor inverter ( 6) and the inverter inverter 7 drives the motor 4 and the generator 5, respectively.

이때 상기 모터용 인버터(6)와 발전기용 인버터(7)에서 출력되는 직류전원은 모두 충전장치(8)와 연결되어 있다At this time, the DC power output from the motor inverter 6 and the generator inverter 7 are all connected to the charging device 8.

따라서 발전기(5)에서 발전되는 에너지는 발전기용 인버터(7)를 통해 충전장 치(8)에 저장되고, 그 에너지는 모터용 인버터(6)를 통해 모터(4)에 인가되어 차량이 구동하게 된다.Therefore, the energy generated in the generator 5 is stored in the charging device 8 through the inverter inverter 7, the energy is applied to the motor 4 through the motor inverter 6 to drive the vehicle. do.

그러나 상술한 바와 같은 종래의 전기 동력 장치에서 모든 발전 에너지는 발전기용 인버터(7)를 통해서 얻어지고 모터(4)의 에너지는 모두 모터용 인버터(6)를 통해서 전달되므로 두 인버터(6, 7)는 차량의 최대 동력 조건을 고려해서 설계되며, 따라서 최대 피크(peak) 파워를 전달할 수 있도록 두 인버터 모두 용량이 매우 커짐에 따라 그 부피와 무게가 커지게 되어 중량이 증가하고 원가가 상승되는 문제점이 발생하고 있다.However, in the conventional electric power unit as described above, all the generated energy is obtained through the inverter inverter 7 and the energy of the motor 4 is transferred through the motor inverter 6, so that both inverters 6 and 7 Is designed in consideration of the maximum power condition of the vehicle. Therefore, both inverters have a very large capacity to increase the maximum peak power. As a result, the volume and weight of the inverter increase, resulting in increased weight and increased cost. It is happening.

또한, 상기 이중권선형 발전기(50)의 회전자 권선과 고정자 권선을 통해 출력되는 전류중 상기 발전기용 인버터(70)에 공급하기 위해 이중권선형 발전기(50) 의 회전자 권선에 유기되는 전원을 수학식으로 정리하면 아래의 수학식 4와 같이 정의할 수 있다.In addition, among the currents outputted through the rotor windings and the stator windings of the double-wound generator 50, power supplied to the rotor winding of the double-wound generator 50 to supply to the inverter inverter 70 is expressed by the following equation: In summary, it can be defined as Equation 4 below.

따라서 도 2에서 개괄적으로 도시되어 있는 바와 같이 엔진(20)의 회전수에 따른 데이터와 바퀴의 회전토크에 대한 데이터를 기준으로 상기 이중권선형 발전기(50)의 회전자 권선과 고정자 권선을 통해 출력되는 전류를 제어할 수 있는 것이다.Accordingly, as shown in FIG. 2, the rotor winding and the stator winding of the dual winding type generator 50 are output based on the data according to the rotation speed of the engine 20 and the data on the rotation torque of the wheel. The current can be controlled.

이와 같이 구성되는 본 발명에 따른 하이브리드 자동차의 전기 동력 장치의 동작을 살펴보면 다음과 같다.Looking at the operation of the electric power unit of the hybrid vehicle according to the present invention configured as described above are as follows.

기존 구조와의 차이는 이중권선형 모터를 사용한 발전기(50)를 이용하고, 발전기의 회전자 권선을 발전기용 인버터(70)에 연결하고, 구동용 모터(40)는 모터용 인버터 없이 이중권선형 발전기(50)의 고정자 권선과 직접 연결하고, 발전기용 인버터(70)의 DC측은 충전장치(80)와 연결하는 구조이다.The difference from the existing structure is using a generator 50 using a double-wound motor, connecting the rotor winding of the generator to the inverter inverter 70, the drive motor 40 is a double-wound generator without a motor inverter ( Directly connected to the stator winding of 50, the DC side of the generator inverter 70 is connected to the charging device 80.

이중권선형 발전기는 고정자뿐만 아니라 회전자에도 권선을 감아서 일반 발전기(동기모터, 유도모터)의 경우 3선이 나오는 반면, 이중권선형은 고정자 3선, 회전자 권선 3선이 나온다.The dual winding generator winds the windings on the rotor as well as the stator, and in the case of general generators (synchronous motors and induction motors), three wires come out, whereas the dual winding type has three stator wires and three rotor windings.

이러한 이중권선형 발전기는 회전자 전류의 크기와 주파수를 가변시켜, 발전기의 고정자 권선에 가변 크기 및 주파수 전압을 유기시킬 수 있다.Such a dual winding generator may vary the magnitude and frequency of the rotor current, thereby inducing a variable magnitude and frequency voltage in the stator winding of the generator.

이상과 같이 본 발명은 모터용 인버터를 사용하지 않고도 모터 제어가 가능하기 때문에 발전기용 인버터의 용량 및 사이즈를 축소할 수 있음으로 차체를 경량화하고 원가를 절감할 수 있는 것이다.As described above, the present invention can reduce the capacity and size of the generator inverter because it is possible to control the motor without using a motor inverter, thereby reducing the weight of the vehicle body and reducing the cost.
