A Half-Bridge Converter With Input Current Ripple Reduction for DC Distribution Systems

DCM Frequency Control Algorithm for Multi-Phase DC-DC Boost Converters for Input Current Ripple Reduction

“…Similarly, the optimum duty for the voltage gain between 3/2 and 3 is 1/3. From (1), the expression for the general selection guide for the N-phase boost converter is given by (7). The visualized duty ratio selection guide of the proposed frequency for the threephase and N-phase boost converter is shown in Fig.…”

“…Therefore, it is necessary to limit the input current ripple through proper equipment or a control method [4][5][6][7][8]. An additional hardware filter can be installed to limit the highfrequency input current ripple on the basis of the switching frequency.…”

“…Several topologies without a filter have been proposed to reduce the input current ripple [4][5][6][7][8]. Reference [5] proposes double-Cúk with a coupled inductor, and it achieves a near-zero input current ripple.…”

“…However, its double-stage configuration and the added passive components may decrease its efficiency and power density. The studies in [6][7][8] employ capacitors and inductors for ripple cancellation, and thus, these topologies also need additional components. Moreover, the operation mode of [7][8] is continuous conduction mode (CCM), which results in switching noise with steep dv/dt and di/dt due to the reverse recovery current of the diode [9].…”

General active stabiliser for coordinated control of low voltage multi‐terminal AC/DC hybrid system

“…With the rapid development of electric vehicles (EVs), energy storage system, light emitting diode (LED) lighting and other DC device, DC power distribution has been widely used [1–5]. Meanwhile, AC equipment is the main form of energy resources and the power demands at present, thus AC/DC hybrid system is becoming a feasible form of distribution network [6, 7].…”
