Hello,
I have been tasked to design an ac constant current source for my school project. The specifications of the design are:
So my approach was to couple the rectifier with the inverter circuit and use PWM to control the output current and frequency, but my design is not working and I am failing to design a control loop for the circuit. Can someone please help
Your help will be much appreciated

I have been tasked to design an ac constant current source for my school project. The specifications of the design are:
- The current source should output 0-16 Amps
- The output frequency of 60-1800 Hz
- The output power of 1000 VA
- The input voltage 230V @ 60 Hz
- THD 10% -15%
- Current regulation of 5% - 15%
- The output should be sinusoidal
So my approach was to couple the rectifier with the inverter circuit and use PWM to control the output current and frequency, but my design is not working and I am failing to design a control loop for the circuit. Can someone please help
Your help will be much appreciated
