Dc dc power converter1/7/2024 ![]() Low power DC converters are available, ranging from 0.25 W to 700 watts.Some latest DC-DC converters are introduced here, along with the basic and new features, so that designers can select the best devices for their applications.ĭC-DC converters are important parts of modern automobiles and industrial applications. The power of a DC/DC converter is expressed in watts. Converters with nominal voltages from 3.3 V to 120 V. alternating current, into direct voltage. They are thus able to convert alternating current (AC), i.e. Some DC converters can be used as inverters. What is the difference between the rated voltages? A distinction is made between solder pads, solder pins, normal pins, spring clips, screw terminals, cable connections and SMD connections.Ĥ. The design depends on the application location and the available space. What type of construction should the housing and pins have? Dealers offer far more than 30 different differentiations.ģ. Starting at 1 mA, DC converters deliver up to 80 Ampere. O Protection against short circuits and reverse polarityĭepending on where the DC/DC converter is used, certain output voltages are possible. O Thermal protection on the device to be installed When is it possible to use a converter permanently?įor permanent use, all protective measures must be checked in advance: Other converter types for an intermediate circuit with storage reactors and capacitors are:įAQ – Frequently Asked Questions about DC/DC Converters and Purchase Criteriaġ. In application with cost-intensive components, which have to deal with the smallest possible number of components, this type of resonance converter is used. The aim is to minimize the power losses as far as possible.ī) Units for small power ranges up to 10 W. A distinction is made between two large modules:Ī) Units for power applications from 1 kW and higher. They represent a class of DC/DC converters of their own. This allows extremely high output voltages to be generated. The voltage is converted by a high-frequency transformer. ![]() The reason for this is the improved efficiency. In contrast to barrier converters, they are designed for higher performance. Infeed transformers are used for power ratings of 100 watts up to 500 watts. In industrial plants, nominal voltages of 24 V, 42 V and 48 V are common. Nominal voltages vary depending on the application area and range from conventional 12 V to 1000 V AC voltages. Due to standards, a tolerance range covers this value. It is used to determine the power consumption during normal operation. The nominal voltage is specified by the manufacturer. The input voltage should not be higher than specified by the manufacturer. Input and output voltageĭC/DC converters can reduce, increase and reverse output voltages. Shielding against interference signals is also an important protection mechanism. This includes temperature, overvoltage and short-circuit protection. To guarantee optimum operating conditions, all necessary protective measures must be checked. The smaller the ratio of the supplied energy to the usable energy, the more effective the converter is. The efficiency is decisive for the effectiveness of the converter. The dielectric strength returns this value. Electrical strength between input and output:Īctive and passive components have a maximum voltage limit for trouble-free operation.
