POWER ELECTRONICS Boost Converter Example: The circuit diagram shown is a boost converter. Assume that no forward conduction loss for diode and switch.

The circuit operates in steady state condition.The switch is closed for time DT and opened for time (1 - D) T.

Calculate:

• a .Output voltage
• b. Capacitor voltage
• c. Inductor current (maximum)
• d. Inductor current (minimum)
• e. Output Current

Sketch the waveform for:

• a. Input voltage
• b. Output voltage
• c. Capacitor voltage
• d. Diode voltage
• e. Inductor voltage
• f. Inductor current
• g. Capacitor current
• h. Output Current
• i. Diode Current
• j. Input Current
