dc-dc converter ckt design
I need help designing a DC-DC converter circuit based on IC UC3524.
The circuit should be designed to obtain a frequency of 3.5KHz.
SPECIFICATIONS:
•Power supply to the circuit = 10V DC.
•The output of the circuit should be PWM (Pulse width modulated) waveform.
•The chopper frequency = 4kHz ±15%.
•The duty cycle should be manually variable from 0 to 100%.
•There circuit should have emergent stop function.
•The block diagram of the circuit is shown in Figure 1.
•The PWM waveform is shown in Figure 2.
DESIGN CONSIDERATIONS:
•The circuit should be designed using UC3524 to obtain the specified frequency and variable duty cycle.
•A MOSFET is used as the switch as shown in Figure 1 and the waveform as in Figure 2.
•After successful testing on resistive load, the circuit is then used to drive a DC motor and realize variable speed control.
Thank alot...
Added after 25 minutes:
Hmm from the converter, I have calculated that the
total resistance = 306 Ω
total capacitor = 0.1 µF (Suggested)
Frequency = 3.5 kHz (FIXED)
Anyone can show me how the circuit can be designed using the UC3524 IC.
Added after 2 minutes:
Can show me more examples and suggestions?
Thank
If you want to sent it to me,
