Web19. aug 2015 · the flat top is caused by rectifier conduction and the spike is rectifier reverse recovery. If you completely disconnect the transformer secondary or load it with a simple … Web6. máj 2024 · It generates four independent sine wave outputs using a quad SPI DAC. As the frequency increases you are getting less samples per period output and the waveform is less sinusoidal (total harmonic distortion THD). You can reduce the THD by adding more entries in your wavetable and decreasing your timer count.

Web7. máj 2024 · Assuming that your voltage and amp value are peak values (maximum of the sine input). This will yield the following power: 5V * 0.707 * 1A * 0.707 = 2.5W. However, keep in mind that this assumes that both the current and voltage are AC in nature with no phase shifting and at the exact same frequency (which for first approximation is most … Web13. mar 2024 · In this tutorial, I am going to demonstrate different methods to generate a sinus wave in an FPGA with Verilog and VHDL. I am going to program and test the functionality with Vivado 2024.4. This is going to be divided into 3 parts: Fixed frequency, variable frequency and a PWM sinusoidal signal.
