조광기 호환형 컨버터 제어 로직 설계{Dimmer-compatible converter logic design}Dimmer-compatible converter logic design

본 발명은 기존 LED 조명용 컨버터의 단순한 기능에 부과적인 조강기능을 구현함에 있어서 간단한 컨버터 로직 설계를 이용해 기존 조광기의 출력신호에 호환이 될 수 있도록 함을 목적으로 한다.
The present invention aims to be compatible with the output signal of the existing dimmer by using a simple converter logic design in implementing the dimming function imposed on the simple function of the conventional LED lighting converter.

일반적으로 사무공간이나 가정의 실내에 설치어 있는 조광기가 가변저항,PWM,또는 0 TO 10v 신호로 조광 기능을 구현 하도록 되어 있다. 이들 조광기의 제어 신호가 각자 달라서 각각에 맞는 컨버터를 설계하거나 CPU통한 신호 변환 과정을 거쳐 제어를 함으로써 시스템이 복잡해지고 추가적인 전력소모를 유발하고 있다.
In general, a dimmer installed in an office space or at home indoors is configured to implement a dimming function with a variable resistor, PWM, or 0 TO 10v signal. The control signals of these dimmers are different, so the system is complicated and additional power is consumed by designing the appropriate converter or controlling the signal through the CPU.

본 발명은 간단한 제어 로직을 통해 추가적인 전력소모를 최소화하고 단순한 연결을 통해 각각의 조광기에 호환할 수 있도록 구성하고자 한다.
The present invention aims to minimize the additional power consumption through simple control logic and to be compatible with each dimmer through a simple connection.

상기의 목적을 달성하기 위한 본 발명은, 기존 조광기의 제어신호들을 간단한 회로를 통해 전력 제어를 위한 신호로 변환시켜 조광기능을 구현하는 것을 특징으로 한다.
The present invention for achieving the above object is characterized in that the control signal of the existing dimmer is converted into a signal for power control through a simple circuit to implement a dimming function.

상기의 회로는 다양한 방식의 조광기 출력신호를 이용해 전력을 제어할 수 있게함으로서 각각의 조광기에 맞는 컨버터를 새로 개발하거나 부가적인 회로를 사용함으로써 발생 되는 비용상승을 막을 수 있다.
The above circuit can control power by using various types of dimmer output signals, thereby preventing the cost increase caused by developing a converter suitable for each dimmer or using additional circuits.

가변저항 조광기 와 0 TO 10 조광기에 호환하기 위한 회로도(그림1)을 살펴보면Looking at the circuit diagram (Fig. 1) for compatibility with the potentiometer and 0 TO 10

보조 전원인 12V를 R2,R3,그리고 R5 값으로 분배를 통해 제어하고자 하는 MAX 전류 기준 값을 정한다. REF1 는 0 ~10V 제어 신호의 MAX 값이므로 10V로 정할 수 있고 10V 이상의 신호 값이 들어와도 D1의 리버스 차단 다이오드를 통해 같은 출력을 유지할 수 있다. CN1의 1번핀을 통해 가변 저항을 연결하면 저항 값에(무한대-> 0) 따라 REF1의 전압 값이 10V에서 점점 낮아지고 이는 전류 기준 값인 REF2의 전압 값을 낮추게 된다. 이때 R4는 최소 전류 값을 보장하기 위해 사용되고 있다. 아울러 같은 핀에 0~10V의 제어 신호가 들어올 경우에도 0일 때 저항 값 0 과 같이 10V일 때 저항 값 무한대일 때처럼 동작한다. 그림2의 R6과 R7은 CN1의 3번 또는 4번 각각 또는 같이 CN1의 5번핀에 단락되는 회로적이거나 기구적인 외부 장치(스위치나,조광장치)를 결합함으로써 REF2의 전압 값을 낮추어서 전류 값을 줄일 수가 있다.또한 R2 또는 R3를 제거하고 CN1의 핀3 또는 핀4 을 통해 PWM신호를 가지고 조광하는 조광장치를 연결하면 R5 와 R6 의 저항 값 분배로 DUTY 1 일때에 MAX 전류 값을 정할 수 있고 DUTY 1 -> 0으로 낮아짐에 따라 출력 전류도 낮아진다. 이때 C1은 PWM 신호가 구형파 이므로 이를 평활하는 용도로 이용된다. CN1 의 1번 PIN 12V 출력은 부수적 시스템인(센서모듈,기타 통신 모듈)을 별도의 전원회로를 구성하지 않고 부착해서 사용할 수 있다. D1과 D2는 복수의 컨버터를 동일한 외부 시스템에 연결 시 다른 전원이 이 컨버터 제어에 영향을 미치는 것을 차단한다. 위의 모든 외부 제어신호(아날로그 또는 디지털)는 OPAMP를 통해 아날로그 신호로 변환되며 이는 메인 전원 IC에 전달되어 출력 전력을 제어하는 구성으로 동작된다.
The 12V auxiliary supply is divided into R2, R3, and R5 to determine the MAX current reference that you want to control. Since REF1 is the MAX value of the 0-10V control signal, it can be set to 10V and the same output can be maintained through the reverse-blocking diode of D1 even if a signal value of 10V or more comes in. Connecting a variable resistor through pin 1 of CN1 causes the voltage value of REF1 to gradually decrease at 10V depending on the resistance value (infinity-> 0), which lowers the voltage value of the current reference value REF2. R4 is used to ensure the minimum current value. In addition, when a control signal of 0 ~ 10V is input to the same pin, it operates as if resistance value is infinite at 10V, such as resistance value 0 at 0. R6 and R7 in Figure 2 lower the voltage value of REF2 by combining a circuit or mechanical external device (switch or dimmer) that is shorted to pin 5 of CN1 or together with CN3 or 4 respectively. Also, if you remove R2 or R3 and connect a dimmer with a PWM signal through pin 3 or pin 4 of CN1, you can set the MAX current value at DUTY 1 by dividing the resistance value of R5 and R6. As DUTY 1 → 0 decreases, the output current also decreases. In this case, C1 is used to smooth the PWM signal because it is square wave. Pin 1V output of CN1 can be used by attaching an additional system (sensor module, other communication module) without configuring a separate power circuit. D1 and D2 prevent different power sources from affecting this converter control when multiple converters are connected to the same external system. All of the above external control signals (analog or digital) are converted to analog signals via OPAMP, which are then delivered to the main power supply IC to operate the output power.

D1,D2는 다이오우드를 나타내며 R1~7 은 저항을 나타낸다. C는 커패시터, 그리고 12V와VPP는 보조전원을 나타내며 기타 로는 OP-AMP를 나타내고 있다.    D1 and D2 represent diodes and R1 to 7 represent resistances. C is the capacitor, 12V and VPP are the auxiliary power, and others are OP-AMP.
