This paper presents a research of full digital-controlled AC/DC converter, which consists of single Boost PFC and LLC resonant DC/DC converter. The whole control system structure is proposed to integrate all analog control functions. By digital control, it can reduce the system's volume and costs, improve characteristics. As a proof of this design, an example of 240W AC/DC converter is given. The...
A switching mode power supply will easily cause serious electro-magnetic interference (EMI) because of the high frequency operation of the power devices. The traditional passive EMI filter (PEF) is bulky and also not efficient in low frequency range. A differential mode active EMI filter (AEF) for DC/DC converter is proposed in this paper. With the analysis and modeling of the full bridge DC/DC converter,...
This study presents a novel topology named high voltage-gain boost DC-DC converter with tapped-inductor. The proposed topology provides a high voltage-gain and low input current ripple which are suitable for alternative power sources such as PV and fuel-cell applications. The interleaved control mode can be used to reduce input and output filtering. Moreover, the voltage stress on MOSFETs are clamped,...
It is of advantage to harvest and dispatch power within a minimal number of conversion steps. This paper proposes a single-stage multi-input multi-output converter (MIMOC), which can be used for interfacing diverse energy sources and loads in future smart homes with dc power distribution architectures. The proposed MIMOC offers compact structure, centralized control, galvanic isolation, and wide voltage...
