Rectifier circuits
Principle: The ripple of the output voltage of various rectifier circuits is measured as a function of the load current strength and the charging capacitance. The characteristics of a voltage stabilizer and of a multiplier are investigated.
Tasks:
1. Using the half-wave rectifier:
a.) to display the output voltage (without charging capacitor) on the oscilloscope
b.) to measure the diode current ID as a function of the output current strength IO (with the charging capacitor)
c.) to measure the ripple component UACpp of the output voltage as a function of the output current (C = constant)
d.) to measure the ripple as a function of the capacitance (IO = constant)
e.) to measure the output voltage UO as a function of the input voltage Ui (IO = 0).
2. Using the bridge rectifier:
a.) to display the output voltage (without charging capacitor) on the oscilloscope
b.) to measure the current through one diode, ID , as a function of the output current Io (with the charging capacitor)
c.) to measure the ripple of the output voltage as a function of the output current (C = constant)
d.) to measure the ripple as a function of the capacitance (Io = constant)
e.) to measure the output voltage as a function of the input voltage.
3. To measure the voltage at the charging capacitor, UC , and the output voltage of a stabilized voltage source as a function of the input voltage Ui .
4. To measure the output voltage of a voltage multiplier circuit as a function of the input voltage.
