This paper proposes a novel single-stage LED driver based on SY5814A for interior-lighting applications with high levels of power factor. High power factor is achieved by constant on-time operation mode, with which the control scheme and the circuit structure are both simple. The proposed driver features cost-effectiveness, high circuit efficiency, high power factor, low input current ripples and a reduced components count. A prototype driver is developed to supply a 15W LED interior-lighting module with a 65V output voltage. Experimental results demonstrate the functionalities of the proposed circuit.

A novel switching mode power supply (SMPS) with input/output isolation is presented, which compounds the three-phase power factor corrector (PFC) with a full bridge converter in a single-stage. It solves the problem of over-voltage on the DC link due to pseudo-phase-shifting control (PPSC) mode. Its operating principle and critical parameters are analyzed. Experiment results of an isolated 10 Kw prototype show that the power factor of the system is above 0.99 and the soft-switching mode reduces most of the EMI.
