Rectifier simulation in Simulink - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define the input AC voltage source in Simulink.

Simulink

input_voltage = [1](2*pi*50*t);

Drag options to blanks, or click blank then click option'

Acos

Btan

Csin

Dlog

💡 Hint

Common Mistakes

Using cosine instead of sine changes the phase but still works, but sine is standard here.

Using tangent or logarithm functions will cause errors or incorrect waveforms.

The input AC voltage is typically modeled as a sine wave using the sin function.

2fill in blank

medium

Complete the code to calculate the peak voltage from the RMS voltage.

Simulink

peak_voltage = [1] * rms_voltage;

Drag options to blanks, or click blank then click option'

A3.1415

B0.707

C2

D1.414

Attempts:

3 left

💡 Hint

Common Mistakes

Using 0.707 instead of 1.414 reverses the conversion.

Using π or 2 are unrelated to this conversion.

The peak voltage is RMS voltage multiplied by the square root of 2, approximately 1.414.

3fill in blank

hard

Fix the error in the code to simulate a full-wave rectifier output voltage.

Simulink

output_voltage = abs([1]);

Drag options to blanks, or click blank then click option'

A-input_voltage

Binput_voltage

Csin(input_voltage)

Dcos(input_voltage)

Attempts:

3 left

💡 Hint

Common Mistakes

Using negative input voltage reverses the waveform incorrectly.

Applying sine or cosine to input voltage is incorrect.

The full-wave rectifier output is the absolute value of the input AC voltage.

4fill in blank

hard

Fill both blanks to create a dictionary of output voltage and current for each time point.

Simulink

results = {t: ([1], [2]) for t in time_points}

Drag options to blanks, or click blank then click option'

Aoutput_voltage[t]

Binput_current[t]

Coutput_current[t]

Dinput_voltage[t]

Attempts:

3 left

💡 Hint

Common Mistakes

Using input current or input voltage instead of output values.

Mixing voltage and current from different points.

The dictionary stores output voltage and output current at each time point.

5fill in blank

hard

Fill all three blanks to filter output voltages above a threshold and create a summary dictionary.

Simulink

summary = {t: [1] for t, [2] in results.items() if [3] > threshold}

Drag options to blanks, or click blank then click option'

Av

B(v, i)

Di

💡 Hint

Common Mistakes

Using current instead of voltage for filtering.

Returning both voltage and current instead of voltage only.

The summary dictionary keeps time points where output voltage (v) is above threshold, storing voltage only.
