Connect the circuit as per the circuit diagram. Give a square wave input as a trigger to pin No. 2. Switch on the power supply. Note down the output waveform at pin No. 3. Calculate the ON and OFF time periods and verify with the theoretical values. 1.1 RC gives theoretical time period. 7. Repeat the above procedure for different values of R. Voltage to Frequency Converter (Voltage Controlled Oscillator): 1. Connect the circuit as per the circuit diagram. 2. Set the input voltage at +5 V. 3.B. Control Circuit of Pulse The block diagram of control circuit is shown in Fig. 2. The pulse is produced by MCU which is dsPIC30F3011 in this design. There are three channels PWM produced by dsPIC30F3011. The first PWM controls the duty 2. Block

Bridge circuit diagram of the constant curfullscale input voltage need a 40 kΩ resistance; the maximum voltage of the input voltage frequency converter module can not exceed 10 V, make VFS as 10 V, therefore, R 1 = VFS/0.25 = 40 kΩ.With a cycloconverter, however, the load voltage is shaped to produce frequency conversion, and the load current is bidirectional to give an ac output. An important parameter defining the performance is the output voltage. In Figs. 1 3. 1 and (ai ib) 1 3. 2 it is seen that M. FIG. 1 Output voltage

FIG. 2 Singlephase cycloconverter (a) circuit diagram for twopulse operation. 398 Chapter 13.The output voltage is the envelope of the voltage at the input of the filter. For this reason these converters are often called the direct envelope frequency converters. The frequency of the output voltage in the presented example (Fig. 8.11) is three times lower than the input voltage frequency. The rms value of the output voltage can be controlled by varying the control angle of the switches (thyristors and triacs).
