본 발명은 펄스폭 변조된 신호의 펄스가 중단될 때에 전기 연결 회로의 유도 인덕턴스에 따라 흐르는 공급전류가 푸퍼 캐패시터에 의해서 저장되는 전체 접속 회로에서 두개 이상의 전기 소모기가 펄스폭 변조된 신호에 의해서 조정되기 위한 방법에 관한 것이다.According to the present invention, in the entire connection circuit in which the supply current flowing according to the induced inductance of the electrical connection circuit is stored by the puffer capacitor when the pulse of the pulse width modulated signal is interrupted, two or more electric consumers are adjusted by the pulse width modulated signal. It is about a method.
이에 대해 펄스폭 변조된 신호가 시간적으로 이동하여 발생되도록 하는 방법이 제안된다.In this regard, a method for generating a pulse width modulated signal by moving in time is proposed.
Description
전기회로에서 전기 소모기가 펄스폭 변조된 신호로 조정될수 있음은 이미 공지되어 있다. 펄스폭 변조된 신호의 센싱 비율에 따라서 전기 소모기와 전압원이 연결 또는 분리된다. 센싱 비율에 따라서 발생된 신호의 펄스가 중단되는 동안에 전압원과 전기 소모기 사이에 전기 연결회로에서 입력 유도 인덕턴스가 발생하므로써 전류가 흐르게 된다. 이러한 전류는 잘 알려져 있듯이 푸퍼 캐패시터에 의해 저저장된다. 만약 전기 회로에서, 예를 들어서 자동차의 클록화된 모터의 최종 단계에서 동일한 센싱 비율을 가진 펄스폭 변조된 신호에 의해서 조정되는 다수의 전기 소모기들이 동시에 연결되어 있으며, 전체의 펄스가 중단된 동안에 이 중단에 따른 캐패시터 고전류가 푸퍼 캐패시터에서 조절된다. 펄스시간 동안에 전체 부하전류와 공급전류의 차이가 푸퍼 캐패시터로부터 흐르고, 따라서 유효 캐패시터 전류가 발생하게 된다.It is already known that in an electric circuit the electricity consumer can be adjusted to a pulse width modulated signal. According to the sensing ratio of the pulse width modulated signal, the electrical consumer and the voltage source are connected or disconnected. While the pulse of the generated signal is interrupted according to the sensing ratio, current flows through the input induced inductance in the electrical connection circuit between the voltage source and the consumer. This current, as is well known, is stored by the hopper capacitor. If in an electrical circuit, for example, at the final stage of a motorized clock of a motor vehicle, a number of electricity consumers are connected at the same time, adjusted by a pulse width modulated signal with the same sensing ratio, while the entire pulse is interrupted. The high current of the capacitor following this interruption is regulated in the poo capacitor. During the pulse time, the difference between the total load current and the supply current flows from the hopper capacitor, so that an effective capacitor current is generated.
공개 공보 WO 88/10367 에는 전기 소모기의 조정을 위한 방법, 즉 상대적으로 큰 부하가 접속될 때에 소모기는 시간적으로 이동되어서, 흐르는 전류가 접속과정중에 연속적으로 상당히 상승하며 그리고 단락 과정중에도 연속적으로 하강하게 되는 접속 또는 단락방법이 공개되어 있다.The publication WO 88/10367 describes a method for the adjustment of an electrical consumer, i.e., when the relatively large load is connected, the consumer moves in time so that the flowing current continuously rises significantly during the connection process and continuously falls during the short circuit process. The connection or short circuit method to be made is disclosed.
본 발명은 청구항 1 항의 전제부의 주안점을 포함한 두개 이상의 전기 소모기를 조정하기 위한 방법에 관한 것이다.The invention relates to a method for adjusting two or more electricity consumers, including the main points of the preamble of claim 1.
도 1 은 접속 회로도.1 is a connection circuit diagram.
도 2 는 펄스폭 변조되는 신호에 따른 유효 캐패시터 전류를 도시한 도면.2 shows an effective capacitor current according to a signal that is pulse width modulated.
청구항 1 항의 전제부를 포함한 본 발명의 방법은 푸퍼 캐패시터의 유효 캐패시터 전류가 감소하게 되는 장점을 제공하게 된다. 적어도 2개 이상의 전기 소모기를 조정하기 위해서 펄스폭 변조된 신호가 발전하여 시간적으로 이동하고, 유효한 펄스의 중단이 감소하며, 이에 따라서 푸퍼 캐패시터의 최대 캐패시터 전류도 감소하게 된다. 또한 캐패시터 전류가 감소하므로써 푸퍼 캐패시터는 예를 들어서 온도와 수명과 같은 상대적으로 비교가능한 주변 조건에 대해서도 상당히 감소되어, 비용 절감을 가져온다.The method of the invention, including the preamble of claim 1, provides the advantage that the effective capacitor current of the hopper capacitor is reduced. The pulse width modulated signal develops and moves in time to adjust at least two or more electrical consumers, reducing the interruption of valid pulses, thereby reducing the maximum capacitor current of the pup capacitor. In addition, by reducing the capacitor current, the hopper capacitor is significantly reduced for relatively comparable ambient conditions such as temperature and lifetime, for example, resulting in cost savings.
본 발명의 유리한 구조에 있어서 펄스폭 변조된 신호는 시간적으로 다음과 같이, 즉 펄스폭 변조된 신호가 중첩되는 경우에 모든 펄스폭 변조된 신호의 동일한 펄스중단이 발생하지 않도록 서로 이동되어 발전된다. 따라서 푸퍼 캐패시터의 전류 유효값이 계속적으로 공급전류에서 캐패시터로 그리고 캐패시터에서 공급전류로 나오게 되어, 유효 최대값이 감소하게 된다.In the advantageous structure of the present invention, the pulse width modulated signals are shifted and developed in time so that the same pulse interruption of all the pulse width modulated signals does not occur when the pulse width modulated signals overlap in time. Thus, the current effective value of the hopper capacitor continues to come from the supply current to the capacitor and from the capacitor to the supply current, thereby reducing the effective maximum value.
본 발명의 유리한 구조는 종속항의 나머지 특징으로부터 나오게 된다.Advantageous structures of the invention emerge from the remaining features of the dependent claims.
본 발명은 이어서 실시예에서 각각에 속하는 도면에 따라 상세히 설명하기로 한다.The invention will next be described in detail with reference to the drawings belonging to each of the embodiments.
도 1에서는 두개의 전기 소모기(12 또는 14)를 구비하고 있는 접속 회로도(10)를 도시하고 있다. 전기 소모기(12 또는 14)는 예를 들어서 자동차 기술에서 적용되고 있는 클록화된 다수의 형태의 직류모터중에 두가지 형태를 말한다. 전기 소모기(12, 14)는, 특히 자동차에서나, 일반적으로 자동차 밧데리에서 각각의 하나의 접속장치(16, 18)에 의해 전압원(20)과 연결된다. 따라서 본원에서 사용접속표시로 도시된 회로 유도성 인덕턴스(L)를 구비한 회로(22)가 연결되어 있다. 전압원(20)과 전기 소모기(12, 14)에 대해서 평행하게 푸퍼 캐피시터(C)가 접속되어 있다.FIG. 1 shows a connection circuit diagram 10 having two electricity consumers 12 or 14. Electric consumables 12 or 14 refer to two of the many types of clocked DC motors that are used, for example, in automotive technology. The electricity consumers 12, 14 are connected to the voltage source 20 by means of one connection device 16, 18, respectively, in particular in motor vehicles or in general in battery batteries. Therefore, a circuit 22 having a circuit inductive inductance L shown here as a connection indication is used. The puffer capacitor C is connected in parallel with the voltage source 20 and the electricity consumers 12, 14.
접속장치(16, 18)은 제어장치(24)를 통해서 펄스폭 변조된 신호에 의해서 조정된다. 각각의 펄스폭 변조된 신호에 따라서 접속장치(16, 18)가 접속되거나 단락된다. 접속장치(16, 18)가 접속된 경우에 전기 소모기(12, 14)는 전압원(20)과 연결되므로써 부하전류가 흐르게 된다. 이와 반대로 접속장치(16, 18)가 단락된 경우에는 회로(22)의 입력 유도성 인덕턴스(L)를 근거로 전압원(20)과 전압과 분리된 전기 소모기(12, 14) 사이에서 공급전류가 흐르게 되며, 이 공급전류는 푸퍼 캐피시터(C)에 의해서 수용된다.The connecting devices 16 and 18 are adjusted by the pulse width modulated signal via the control device 24. The connecting devices 16 and 18 are connected or shorted according to the respective pulse width modulated signals. When the connecting devices 16 and 18 are connected, the electric consumers 12 and 14 are connected to the voltage source 20 so that a load current flows. On the contrary, when the connection devices 16 and 18 are short-circuited, the supply current is provided between the voltage source 20 and the electric consumables 12 and 14 separated from the voltage based on the input inductive inductance L of the circuit 22. Flows, and this supply current is received by the hopper capacitor (C).
접속장치(16, 18)가 접속된 경우에, 즉 전압원(20)과 전기 소모기(12,14)가 연결된 경우에 전체의 부하전류와 푸퍼 캐피시터로 가는 공급전류 사이의 차이와 동일한 공급전류에 의해서 푸퍼 캐피시터(C)가 방전된다. 따라서 접속장치(16, 18)의 위치에 따라서 푸퍼 캐피시터(C)용 전류가 확실히 조절된다.When the connecting devices 16 and 18 are connected, i.e. when the voltage source 20 and the electric consumables 12 and 14 are connected, the supply current equal to the difference between the total load current and the supply current to the puffer capacitor is The puffer capacitor C is discharged by this. Therefore, the current for the puffer capacitor C is surely adjusted in accordance with the positions of the connection devices 16 and 18.
다이어그램에서 규정된 유효 캐패시터 전류(I)를 센싱 비율(T)로 펄스폭 변조된 제어장치(24)가 접속장치(16, 18)에 의해 조정되는 것을 도 2 에 도시하고 있으며, 캐패시터 전류(I)의 유효값에 미치는 센싱 비율의 영향을 뚜렷하게 관찰할 수 있다.The control device 24, which is pulse-width modulated at the sensing ratio T by the effective capacitor current I defined in the diagram, is adjusted by the connecting devices 16, 18, and the capacitor current I The effect of the sensing ratio on the effective value of) can be clearly observed.
접속장치(16, 18)가 펄스폭 변조된 신호로 클록과 동일하게 조정될 때에, 즉 접속장치(16, 18)가 동시에 접속 또는 단락될 때에, 전류(I)의 유효값의 진행을 종래의 기술에 따라 제 1 특성곡선(26)에 도시하고 있다.When the connecting devices 16 and 18 are adjusted in the same manner as the clock with the pulse width modulated signal, that is, when the connecting devices 16 and 18 are connected or shorted at the same time, the progress of the effective value of the current I is known. The first characteristic curve 26 is shown as follows.
전류(I)가 유효값으로 진행되기 위한 또다른 특성 곡선이 표시부호 28 로 나타나 있으며, 이 경우에는 전기 소모기(12, 14)가 시간적으로 이동되어 동일한 센싱 비율로 된 펄스폭 변조된 신호로 조정하게 되며, 따라서 센싱 비율에 따라서 접속장치(16, 18)는 서로 다른 시간 포인트에서 접속되거나 단락된다. 이에 따라서 접속장치(16, 18)가 시간적으로 이동 조정됨으로써 짧은 펄스 중단이 발생하고 (접속장치(16,18)의 펄스폭 변조된 두 신호의 중첩으로 발생된 짧은 펄스 중단), 따라서 캐패시터 전류의 최대 유효값이 확실히 감소하게 된다.Another characteristic curve for the current (I) to proceed to the effective value is indicated by the reference sign 28, in which case the electricity consumers 12, 14 are shifted in time to form a pulse width modulated signal with the same sensing ratio. The connections 16 and 18 are thus connected or shorted at different time points depending on the sensing ratio. This results in a short pulse interruption as the connections 16 and 18 are moved in time and adjusted (short pulse interruptions resulting from the superposition of two pulse-width modulated signals of the contacts 16 and 18), thus reducing the capacitor current. The maximum effective value is certainly reduced.
특성곡선(26, 28)에 따라서 50%의 센싱 비율의 경우(전체 주기기간에 대한 펄스폭 변조된 신호의 시간 경과) 그리고 접속장치(16, 18)의 동일한 센싱 비율로 펄스폭 변조된 신호로 주기 기간의 1/2 로서 시간 이동되어 제어된 경우에 유효 전류(I)의 최소값이 발생하게 된다. 정확히 주기 기간의 1/2 로 이동되어 펄스폭이 변조된 신호와 정확히 각각의 센싱 비율의 50 % 로 가정된 이상적인 관계에서는 유효 전류(I)가 0 이 되므로써, 푸퍼 캐피시터(C)는 더 이상 필요하지 않다. 그러나 펄스폭 변조된 신호의 변환은 신호의 종단측면에 의해서 이루어지기 때문에 0 의 값은 실제적으로 도달할 수 가 없다. 도시된 특성곡선(26, 28)에서는 다른 센싱 비율의 경우에 최대 유효전류(I)값이 뚜렷히 감소됨을 보여주고 있다. 따라서 유효 전류(I)의 감소에 따라서 푸퍼 캐피시터(C)는 이에 따라서 소형으로 설계될 수 있다.According to the characteristic curves 26 and 28, the sensing ratio of 50% (time lapse of the pulse width modulated signal over the entire period) and the pulse width modulated signal at the same sensing ratio of the connecting devices 16 and 18 are obtained. The minimum value of the effective current I occurs when it is time-shifted and controlled as half of the period. In an ideal relationship where the pulse width is shifted exactly 1/2 of the period and assuming that the pulse width is exactly 50% of each sensing ratio, the effective current I becomes zero, so that the puffer capacitor C is no longer needed. Not. However, since the conversion of the pulse width modulated signal is made by the signal's end side, the value of 0 cannot actually be reached. The characteristic curves 26 and 28 shown show that the maximum effective current (I) value is clearly reduced for different sensing ratios. Therefore, as the effective current I decreases, the puffer capacitor C can be designed accordingly accordingly.
제 3 의 특성곡선(30)으로서 전체 부하전류의 진행 과정이 센싱 비율에 따라 접속되는 전기 소모기(12, 14)에 도시되어 있다.As the third characteristic curve 30, the progression of the total load current is shown in the electric consumers 12, 14 connected in accordance with the sensing ratio.
