I am looking for parts or application notes that can help me with the design of a 60Hz to 400Hz Sine Wave converter.
Basically the input to the system is a 60Hz Sine Wave that is rectified, filtered to DC and then converted to 400Hz Sine Wave via Pulse Width Modulation and LC filters. I already have a way of generating a 400Hz reference signal. A switching speed of 50kHz to 100kHz would be ideal with a value corresponding to a multiple of 400 so 50kHz, 50.4kHz, 50.8kHz, etc. The output of which would then be used in a Full Bridge setup. A similar design to what I am trying to do can be found at http://www.wpi.edu/Pubs/E-project/Available/E-project-042507-092653/unrestricted/MQP_D_1_2.pdf.
As can be seen in the above document, the authors rely on operational amplifiers a lot. I want to update it and replace a lot of the PWM portion of the system, ramp generator, comparator, etc., with a single chip if possible. I have designed the system to this point with bipolar supplys. Power at the transistors is +/- 310V. I can make the power available for logic anywhere from +/- 5V to +/- 16V.
Thank you for the help.
