About This Course
DC DC Converters are electronic devices that convert DC electric power from one voltage level to another.
They are used in UPS (uninterrupted power supply), solar power generation stations, fuel cell-based power generation units, chargers, EVs, HEVs and electronic control units (ECUs). The DCDC converters that step down the voltage (output voltage is less than input voltage) are called buck converters and the DCDC converters that step up the voltage (output voltage is more than the input voltage) are called boost converters.
DCDC converters include passive potential dividers, linear regulators, charge pumps and switch mode converters.
Potential dividers and linear regulators are used as buck converters for low power applications. The charge pumps are used as boost converters for low power applications. While switch mode converters can be used as buck or boost DC converters for high power applications.
The criteria for selection or the design of DCDC converters are :
Input and output voltage range 2. Power ratings 3. Efficiency 4. Isolation/non-isolation 5. Cost 6. Size 8. Ripple factor 9. Harmonic injection at input source.
At the end of each training session, assignments are given to judge the understanding of the topics discussed.
