What are the basic types of DC-DC converter?
There are two types of DC/DC converters: linear and switched. A linear DC/DC converter uses a resistive voltage drop to create and regulate a given output voltage, a switched-mode DC/DC converts by storing the input energy periodically and then releasing that energy to the output at a different voltage.
What does DC converter mean?
direct current
A DC-to-DC converter is an electronic circuit or electromechanical device that converts a source of direct current (DC) from one voltage level to another. It is a type of electric power converter.
What do you need to know about DC to DC converters?
Hit Enter to Search DC-DC Converter Basics. ABSTRACT. A DC-to-DC converter is a device that accepts a DC input voltage and produces a DC output voltage. Typically the output produced is at a different voltage level than the input. In addition, DC -to-DC converters are used to provide noise isolation, power bus regulation, etc.
Which is an example of an isolated DC / DC converter?
Unregulated isolated DC/DC converters, also known as open-loop isolated DC/DC converters, are widely used in applications that don’t require precise output voltage. A typical example is the push-pull converter with fixed 50% duty cycle (Figure 3).
Do you need an optocoupler for an isolated DC converter?
Conversely, regulated isolated DC/DC converters provide tight output voltage regulation, but require an optocoupler. There are many applications where the customer may not want an optocoupler, but require the output voltage to be regulated to some extent.
How does a DC / DC converter control circuitry work?
The control circuitry consists of only an oscillator along with two gate drivers, which generates two complimentary fixed 50% duty cycle gate signals to drive Q1 and Q2. The transformer turns ratio is selected to deliver the desired output voltage. Neither a feedback circuitry nor a signal isolator is required, which reduces cost and solution size.
