Pulse Width Modulation Signals Card
This practical resource allows students to investigate the principles of pulse width modulation signals, through a range of practical activities.
The practical activities based around the Pulse Width Modulation Signals Card (320-50) are available within the digital curriculum materials provided with our Electronics Study Trainer.
Practical tasks include the following:
- PWM signal driving an LED
- PWM signal – variable frequency and duty cycle
- PWM motor speed control circuit
- Investigation of a sensorless motor speed control signal
- Investigation of a 3-phase waveform
- 3-Phase inverter driver circuit
- PWM to 3-phase drive signal
- 3-Phase bridge rectifier circuit
- Rectifier with DC smoothing capacitor
- Fault-finding signal conditioning circuits
Please Note: This card requires access to an Electronics Study Trainer (320-00).
