Week 4 Session 5

Explain the various applications of Power converters in an Electric vehicle. For Example what type of converter will you use for Horn which requires DC and less than 10V. Likewise come up with different applications

Ans: EV converters are classiffied into two:

1. Non Isolated converter
2. Isolated converter

Non-isolated converters are:

• Buck Converter:

• The buck converter is a step-down converter and produces a lower average output voltage than the dc input voltage.

  • Boost converter:

  In the boost converter, the output voltage is always greater than the input voltage.

  • Buck-Boost converter:

  In a buck-boost converter, the output voltage can be either higher or lower than the input voltage.

  • Cuk converter:

  The output voltage can be either higher or lower than the input voltage providing some advantages over buck-boost (like a continuous current, less current ripple etc.)

  • SEPIC converter:

  The output voltage can be either higher or lower than the input voltage (with no polarity reversal compared to Buck-boost or Cuk converter).

• Isolated converters are:
• Half Bridge converter
• Full Bridge Converter
