A Beat Frequency Modulation (BFM) system for generating a low frequency reference waveform including two or more converters, a frequency control module, and a rectifier. The converters are connected in series, parallel, or cascaded. Each converter includes a power switch configured to generate a high frequency power signal controlled by BFM modules at their respective outputs. The frequency control module is configured to operate a BFM carrier signal of each of the converters at different frequencies, thereby creating an envelope of a resulting signal containing a desired low frequency reference signal. The rectifier is connected to outputs of the converters and configured to rectify the high frequency signal with the low frequency envelope shape, thereby generating a low frequency sinusoidal waveform.
