What is a DCDC converter?

Current and voltage controlled DCDC converters for ultracapacitors, batteries, fuel cell, peak shaving and voltage stabilizers applications. DCDC Converters are becoming more and more important for grid applications and many renewable power supplies are operating on DC voltage.

What is a non-isolated high-gain Step-Up DC–DC converter?

In this manuscript, introduce a non-isolated high-gain step-up DC–DC converter designed for fuel cell-based electric vehicles. This converter enhances voltage gain without resorting to voltage multiplier units, transformers, or coupled inductors. A key advantage is its streamlined component count.

Does a step-up DC–DC converter increase voltage gain?

Experimental results of output voltage, inductor currents, and the voltage across the capacitor. In this manuscript, introduce a non-isolated high-gain step-up DC–DC converter designed for fuel cell-based electric vehicles. This converter enhances voltage gain without resorting to voltage multiplier units, transformers, or coupled inductors.

What is the voltage transfer gain of a DC–DC converter?

The voltage transfer gain of the proposed DC–DC converter when operating in CCM is given by Eq. (46). It can be observed that the voltage gain ratio equations of the proposed converter in DCM and CCM exhibit higher voltage gain ratios than those of previous DC–DC converters, as shown in Table 2.

What is a high-gain DC converter based on a diode-capacitor multiplier?

A high-gain DC converter based on diode-capacitor multipliers and coupled inductors is suggested in 22. It can give higher output voltage gain at a lesser duty cycle and low power device stress.

Can a DC-DC converter supply a variable high-output voltage?

In addition, the proposed DC–DC converter can supply variable high-output voltage between 200 and 400 V, making it more suitable for a wide range of applications. Furthermore, a dual PI controller is designed for the proposed converter to maintain a fixed output voltage under variable load and input voltage conditions.
