Research on Electric-Fluid Mechanics with Intermittent Oscillatory of RCC Circuit

Abstract:

RCC circuit (self-oscillating flyback converter) is a kind of high efficient working circuit by use of several devices, but excessive control current will cause the occur of intermittent oscillation. And then the oscillation frequency of the circuit change in a large scope (from hundreds of hertz to several thousand hertz). In addition, the output power is more likely to make the transformer device to produce abnormal noise. However, this phenomenon is not completely useless. After improving the RCC circuit can be conclude that the circuit can start in applying a pulse signal if the output power is small. The switch circuit operates in low-power state by means of intermittent oscillation. The result is that RCC circuit have high performance price ratio and low cost, so it is a widely used in high performance power supply equipment.
