Advantages of DC-DC converter,disadvantages of DC-DC converter
This page covers advantages and disadvantages of DC to DC converter and its basics/types. It mentions benefits or advantages of DC-DC converter and drawbacks or disadvantages of DC-DC converter.
What is DC-DC converter?
A dc-dc converter is electronic circuit. The main function of this circuit is to modify one potential difference(i.e. voltage) level to the another potential difference level. It is basically a voltage regulator consisting of switches, inductor and capacitor for power conversion. There are numerous applications of DC-DC converter. It's major application is steady switch mode dc power supply.
Following are the main reasons for its wide spread use in electronic circuits.
• To simplify power supply systems.
• To isolate primary circuit and secondary circuit.
• To match the loads to the power supply.
Selection of DC to DC converter depends on several parameters as mentioned below.
• Input voltage, Output voltage
• Output power
• Safety (Isolated or non-isolated)
DC-DC converters are divided into following types based on isolation between input and output circuits.
• Isolated DC-DC converter
• Non-isolated DC-DC converter
Isolated DC-DC converters are further divided into following sub types.
• Fly-back (As shown in the figure)
• Half bridge
• Full bridge
• Push Pull
Benefits or advantages of DC-DC converter
Following are the benefits or advantages of DC-DC converter:
➨It provides technique to extend potential from partly reduced cell potential.
➨It is available as whole hybrid circuit element and requires very few additional components.
➨DC to DC choppers are used to regulate the voltage.
➨It is constructed to make best usage of the energy yield for photo-voltaic systems.
➨Isolated DC-DC converter has more energy transformer on condition of the barrier.
➨The output of isolated converter is organized as positive or negative.
Drawbacks or disadvantages of DC-DC converter
Following are the drawbacks or disadvantages of DC-DC converter:
➨Switching converters are prone to noise.
➨They are expensive.
➨Choppers are inadequate due to unsteady voltage and current supply.
➨Disadvantages of fly-back type: More EMI due to gap, More ripple current, More input/output capacitance, higher losses etc.
Conclusion: In order to understand advantages of DC-DC converter and disadvantages of DC-DC converter one has to understand DC-DC converter basics and its types.
