이 고안은 전원공급장치(Switching Mode Power Supply : SMPS)에 관한 것으로서 더욱 상세하게는 공진 캐패시터를 부하와 직.병렬로 연결시킴으로써 전류제한 및 주부하의 경우에도 제어가 가능하도록한 직.병렬 부하를 갖는 직렬 공진 컨버터에 관한 것이다.The present invention relates to a switching mode power supply (SMPS), and more particularly, by connecting a resonant capacitor in parallel with a load in parallel with a load to allow control even in the case of current limiting and main load. It relates to a series resonant converter.
제1도는 종래의 직렬 부하를 갖는 직렬 공진 컨버터 회로를 나타낸 것으로서 부하(1)가 공진 캐패시터(CR)와 직렬로 연결되어 있음을 보여준다.FIG. 1 shows a series resonant converter circuit having a conventional series load, showing that the load 1 is connected in series with the resonant capacitor CR.
이러한 직렬부하를 갖는 직렬 공진 컨버터에서는 전류제한은 잘되나 무부하의 경우에는 공진계수(Q)가 너무 낮아 제어 루프 이득으로는 출력 전압을 조절하기가 어렵다는 문제점이 있었다.In the series resonant converter having such a series load, the current limit is good, but in the case of no load, the resonance coefficient Q is too low to control the output voltage with the control loop gain.

The load 2 and the resonant capacitor CR are connected in parallel. The series resonant converter having such a parallel load can be controlled in the case of no load, but the resonant capacitor CR There was a problem that there is excess power stress.
이 고안은 이러한 문제점을 해결하기 위한 것으로서 이 고안의 목적은 공진 캐패시터를 부하와 직.병렬로 연결시켜 전류 제한 및 무부하의 경우에도 제어가 가능하도록 한 직.병렬 부하를 갖는 직렬공진 컨버터를 제공하고자 함에 있다.The object of the present invention is to provide a series resonant converter having a series and a parallel load in which a resonant capacitor is connected in parallel with the load so that it can be controlled even under current limitation and no load. It is in a ship.
이러한 목적을 달성하기 위한 이 고안의 특징은 주파수 변조에 의한 출력 레귤레이션부와, 상기 출력 레귤레이션부에 피이드백되어 연결된 부하와, 상기 주파수 변조에 의한 출력 레귤레이션부의 제어에 의해 교대로 턴온되어 전류루프를 형성시키는 스위치와, 상기 스위치 사이에 병렬로 타측과 연결된 공진코일과, 를 포함하여 구성되는 공진 컨버터에 있어서, 입력단 및 부하에 직렬로 연결된 공진 캐패시터와, 상기 부하에 대응하는 트랜스의 1차측에 부하와 병렬로 연결된 공진 캐패시터와, 를 더 포함하여 구성되는 직, 병렬 부하를 갖는 직렬 공진 컨버터에 있다.A feature of the present invention for achieving this purpose is to alternately turn on the current loop by the output regulation part by frequency modulation, the load fed and connected to the output regulation part, and the control of the output regulation part by the frequency modulation. A resonant converter comprising: a switch to be formed, a resonant coil connected to the other side in parallel between the switches, and a resonant capacitor connected in series with an input terminal and a load, and a load on a primary side of a transformer corresponding to the load. And a series resonant capacitor connected in parallel with and a series resonant converter having a direct and parallel load.
이하, 이 고안의 바람직한 일실시예를 첨부도면을 참조로 하여 상세히 설명한다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
제3도는 이 고안에 따른 직.병렬 부하를 갖는 직렬 공진 컨버터 회로도로서, 주파수 변조에 의한 출력 레귤레이션부(10)에 피이드백으로 부하(20)를 연결시킨다.3 is a series resonant converter circuit diagram having a series and parallel load according to the present invention, and connects the load 20 to the output regulation unit 10 by frequency modulation by feedback.
한편, 입력측에는 부하(20)와 직렬로 연결된 공진 캐패시터(CR1), (CR2)를 연결시키고 상기 공진 캐패시터(CR1), (CR2)사이와 부하(10)에 대응하여 연결된 트랜스(T1)의 1차측(L1)에는 병렬로 공진캐패시터(CR3)를 연결시킨다.On the other hand, the resonant capacitors CR1 and CR2 connected in series with the load 20 are connected to the input side, and 1 of the transformer T1 connected between the resonant capacitors CR1 and CR2 and corresponding to the load 10. The resonant capacitor CR3 is connected to the vehicle side L1 in parallel.
그리고 상기 공진 캐패시터(CR3)에는 공진 코일(LR)을 연결시키며 입력측에는 상기 주파수 변조에 의한 출력 레귤레이션부(10)의 제어에 의해 교대로 턴온되어 전류 루프(i1),(i2)를 형성하는 스위치(SW1), (SW2)를 연결시킨다.The resonant capacitor CR3 is connected to the resonant coil LR, and the input side is alternately turned on by the control of the output regulation unit 10 by the frequency modulation to switch to form the current loops i1 and i2. Connect (SW1) and (SW2).
상기와 같이 구성된 이 고안은 전압이 인가되면 주파수 변조에 의한 출력 레귤레이션부(10)의 제어에 의해 스위치(SW1), (SW2)가 교대로 턴온됨에 따라 전류 루프(i1), (i2)가 형성되며 부하(20)에도 전압이 유기된다.According to the present invention, the current loops i1 and i2 are formed as the switches SW1 and SW2 are alternately turned on by the control of the output regulation unit 10 by frequency modulation when a voltage is applied. The voltage is also induced in the load 20.
상기와 같이 주파수 변조에 의한 출력 레귤레이션부(10)의 제어에 의해 스위치(SW1), (SW2)가 교대로 턴온되어 전류 루프(i1),(i2)가 형성됨에 따라 공진 컨버터로써 작용하는 방식을 하프-브리지 방식의 공진 컨버터라한다.As described above, the switch SW1 and SW2 are alternately turned on by the control of the output regulation unit 10 by the frequency modulation to act as a resonant converter as the current loops i1 and i2 are formed. It is called a half-bridge resonant converter.
한편, 공진 캐패시터(CR1), (CR2)는 용량성 소자로서 부하(10)와 직렬로 연결되어 있음에 따라 전류 제한의 역할을 하며 공진 캐패시터(CR3) 또한 용량성 소자로서 부하(10)와 병렬로 연결됨에 따라 무부하의 제어가 가능하도록 한다.On the other hand, the resonant capacitors CR1 and CR2 are capacitive elements and are connected in series with the load 10 to act as a current limiter, and the resonant capacitor CR3 is also parallel to the load 10 as the capacitive element.
