An average model of SEPIC converters with coupled or uncoupled inductors was developed and verified against cycle-by-cycle s i m u l a t i o n s . The model can be used as-is by any modern circuit simulator to run steady state (DC), large signal (transient) and small signal (AC) analyses. The leakage inductances were taken into account and treated separately from the mutual inductance. The prim...

Silicon integrated circuit spiral inductors and transformers are analyzed using electromagnetic analysis. With appropriate approximations, the calculations are reduced to electrostatic and magnetostatic calculations. The important effects of substrate loss are included in the analysis. Classic circuit analysis and network analysis techniques are used to derive two-port parameters from the circu...

This project, along with the voltage multiplier chain with dual coil output to the boost converter provides a novel parallel input. On the one hand, and to take part in the input current and to reduce input curre nt ripple in the two coils in parallel with the primary windings connected. On the other hand, it is proposed to change, and a series of interleaved output capacitors profit profitable...

Many applications call for high step-up dc–dc converters that do not require isolation. Some dc–dc converters can provide high step-up voltage gain, but with the penalty of either an extreme duty ratio or a large amount of circulating energy. DC–DC converters with coupled inductors can provide high voltage gain, but their efficiency is degraded by the losses associated with leakage inductors. C...

In this paper, a new coupled-inductor based modular multilevel cascaded inverter using phase-shift control is presented. The proposed can generate high output ac voltage standard low rating devices. number of levels in the pulse width modulation (PWM) and effective switching frequency filter are increased coupled inductors control. signals units phase-shifted by 360°/4n, where n units. r...
