![]() But we can reduce harmonics to some extent using a simple low pass LC filter. In a general way, it is said that getting an absolutely clear signal is impossible. Signal conditioning offers signals of the pure form i.e., free from harmonics. A power electronic converter is composed of power semiconductor devices controlled by integrated circuits.Īn important aspect of converters is signal conditioning. We have already discussed that power electronic devices are a combination of converter and controller where the converter functions according to the control signal generated by the controller. This conversion of energy provides voltage and current in such a form that suits various user requirements. In our previous content, we have discussed that power electronic technology handles the controlling process of conversion of one form of electric energy into another form. Isolated DC-DC converters are safer to use in cases of internal failure as they prevent the input voltage from being transmitted to the output.Power Converters have turned out to be a crucial component of the household as well as commercial equipment. Charge-Pump – This converter is used for stepping the voltage up or down in applications that have low power.ĭriving a device by increasing or decreasing the available input voltage prevents damage or breakdown.The Cuk was named after Slobodan Cuk, the man who created it. The biggest difference is really the name. Cuk – This type of converter is similar to buck-boost converters.Boost DC-DC converter - does the opposite to the Buck and steps up the voltage output.Buck DC-DC converter - named because it 'bucks' against the input voltage, this device produces an output that is less than its input. ![]() Portable car power adaptor - the converters take the DC power that comes in from the vehicle's battery and step it down to make it usable with personal devices such as DVD players, phone connectors, CD players and more.One disadvantage is that they do not offer much protection against high electrical voltages. Non-Isolated DC-DC converters - these devices do not have any isolation between the input and output and are typically used for smaller voltages.They have higher isolation voltage properties and unlike the non-isolated version have the ability to block noise and interference. Isolated DC-DC converters - in these the output is isolated from the input with internal transformers to convert the input to a different output voltage.It's important to know the specifications of the converters being used to avoid damaging equipment. Some DC-DC converters will step up the power, others will step down and some can do either. Types of DC-DC ConvertersĪ wide variety of types are available to suit different needs. So it's necessary to use a converter to drop the power and make it safe for the device. Sometimes it is necessary to convert the power, for example, from a 24V truck battery to 12V in order to power a car radio. Why is it necessary to convert DC to DC?ĪC power allows the variation of voltage levels via a transformer, unfortunately this doesn't work with DC power. They are used where the operating voltage for some electronic devices vary making it necessary to provide a separate voltage for each device. As the name implies a DC-DC converter is an electronic circuit or electromechanical device which takes a source of direct current (DC) and converts it from one voltage level to another.
