“…The time duration when SW is turned off (i.e. mode 2 and 3) is (1-D)T. The current i D1 , which is a charging current from L m to C 1 , has a triangle shape similar to that in the clampmode boost converter [12]. The current i D2 , which is a discharging current from C 1 to C 2 , is approximated by a pulse current with an amplitude I p .…”

“…During this turn-off interval, the output voltage is given by the sum of the input voltage and the induced voltages on the primary and secondary windings, which are additive. It is shown in [11,12] that the voltage gain and clamp voltage of the clamp-mode coupledinductor boost converter are given by…”

“…In this respect, the advantage of the coupled inductor converters over the cascade converter becomes distinct when the output voltage is high. Among many coupled inductor converters, a clamp-mode coupledinductor boost converter [12] is a very attractive topology. Its salient features include: (1) a simple circuit structure using only one power switch, (2) high voltage gain controlled by the coupled inductor's turn ratio, (3) a switch voltage clamp reducing the device voltage stress, and (4) high efficiency.…”

“…The main drawbacks of this topology, nonetheless, are high current and voltage stresses associated with the power switch, and the low efficiency due to multi-stage power processing. High gain DC-DC converters based on a coupled inductor [11][12][13][14][15][16][17][18][19][20][21] can overcome the efficiency and voltage stress problems of the aforementioned cascade converter. The coupled inductor converters achieve the high voltage gain by utilizing the coupled inductor's turn ratio, instead of cascading multiple boost stages, hence leading to the improved efficiency.…”

-In this paper, a new coupled inductor DC-DC converter with a high step-up voltage gain is proposed. It is developed from a clamp-mode coupled-inductor boost converter by incorporating an additional capacitor and diode. The proposed converter is able to achieve the higher voltage gain, while still retaining the switch voltage clamp property of its predecessor. In the paper, operation and analysis of the proposed converter are described. Experimental results from a prototype converter are presented to verify the validity of the analysis. The prototype circuit attains the highest efficiency of 92.8%.

“…This new class of converters uses high-frequency transformers to provide a more efficient path for the energy to flow from the source to the load. Works have been done in order to analyse the different topological variations of these converters [5], in order to achieve high efficiency with a high conversion ratio, and low stress on the components. The characteristics of these converters make them attractive to applications where high output voltages are required when the voltage source can provide only low voltages.…”

Abstract-Step-up dc-dc power converters are needed in many applications. Depending on the voltage conversion ratio, one or another structure should be chosen, usually leading to efficiency vs. conversion ratio trade-offs. Recently, a new class of switchmode dc-dc power converters has been introduced into the literature. These new converters show high efficiency levels at high conversion ratios, making them attractive to applications where efficiency is a major concern. Due to the complexity of the structure, mathematical models of the system have not been developed up to now, making the closed-loop control of these devices a challenging task. In this paper, an output voltage regulation control scheme is proposed and tested in simulation. The system is decomposed in subsystems, whose models are identified within the different control stages.

The large-signal averaged model of a coupled-inductor double-boost converter is developed and analysed in this paper. Due to the large current fluctuations, the differential system is deduced by averaging the circuit equations of the operation modes over a switching period. Generic expressions that permit to calculate the current commutation intervals as function of the averaged state variables are also found to complete the model. Resistive losses are introduced into an equivalent averaged circuit leading to a more realistic scenario. The proposed state-space model is used for studying voltage conversion ratios, transients and frequency-domain responses of the converter as well as for designing a control loop that regulates the output voltage. Numerical simulations and experimental measurements corroborate the obtained results. Keywords DC-DC converter • High conversion ratio • Averaged model • Dynamical behaviour
