Hysteresis control technique in Power Electronics - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define the hysteresis band width variable.

Power Electronics

hysteresis_band = [1]

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

A0.1

B10

C1.0

D0.05

💡 Hint

Common Mistakes

Using a very large value for the hysteresis band width.

Setting the band width to zero, which disables hysteresis.

The hysteresis band width is typically a small positive value like 0.05 to control switching.

2fill in blank

medium

Complete the code to check if the output current exceeds the upper hysteresis limit.

Power Electronics

if current > set_point + [1]:

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

Aset_point

B0

Chysteresis_band

Dcurrent

💡 Hint

Common Mistakes

Comparing current to set_point without adding the hysteresis band.

Using zero instead of the hysteresis band.

The upper limit is the set point plus the hysteresis band width.

3fill in blank

hard

Fix the error in the condition to check if current is below the lower hysteresis limit.

Power Electronics

if current [1] set_point - hysteresis_band:

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

A>

B<

C==

D>=

💡 Hint

Common Mistakes

Using greater than instead of less than.

Using equality operator which is too strict.

The condition should check if current is less than the lower limit (set_point minus hysteresis band).

4fill in blank

hard

Fill both blanks to complete the hysteresis control logic for switching.

Power Electronics

if current [1] set_point + hysteresis_band:
    switch_state = [2]

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

A>

BTrue

CFalse

D<

Attempts:

3 left

💡 Hint

Common Mistakes

Using '<' instead of '>' in the condition.

Setting switch_state to True when current is too high.

If current exceeds the upper limit, the switch should turn off (False).

5fill in blank

hard

Fill all three blanks to complete the hysteresis control logic for turning the switch on when current is below the lower limit.

Power Electronics

if current [1] set_point - hysteresis_band:
    switch_state = [2]
else:
    switch_state = [3]

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

A<

BTrue

CFalse

D>

Attempts:

3 left

💡 Hint

Common Mistakes

Using '>' instead of '<' in the condition.

Reversing True and False for switch_state.

If current is less than the lower limit, switch turns on (True), else off (False).
