Abstract :
In this paper, a particular phenomenon called indirect synchronization is investigated on self-oscillating current controllers. This phenomenon appears in medium frequencies, when the reference signal frequency tends to the switching frequency. In a previous work, it has been shown that the indirect synchronization causes discontinuities on the frequential response of the system, making the various linear or continuous models inefficient. For high-accuracy applications, such as active filtering or high-precision power supply, these discontinuities are a real problem. Thus, it seems important to offer an analytical description of this phenomenon. In this paper, an analytical model of the indirect synchronization phenomenon is proposed and checked by simulation and experimental results.
