I have developed a sine wave generator with DDS chip AD9833.
AD9833 has an output signal of 0,6 Vpp. I use AD9833 to generate a sine wave at a frequency of 50 Hz and use a microcontroller to change the frequency (40-400Hz).
The signal is amplified up to 4Vpp and with a digital potentiometer I control the amplitude.
How to amplify the signal to obtain a sinewave 230Vrms?
The required power is 150VA. I wish there was a transformer (for example 24V/230V) for insulation.
Any idea?
I suggested an electrical schematic?
