Magic sinewaves are ultra long repeating binary sequences highly useful for induction motor speed controls, electric autos, solar inverters, and home energy efficiency improvers. Compared to traditional PWM, magic sinewaves offer lower costs, higher efficieny, elegant simplicity, simplified filtering, and involve significantly less high frequency energy.

Additional details on magic sinewaves appear on www.tinaja.com

This is a preliminary sequence of three phase "delta friendly" magic sinewaves. The 49 available amplitudes are optimized for low distortion combined with reasonable jitter and efficiency.

Only the first quadrant of the "a" phase sequence is shown. The "b" phase sequence is delayed by 120 degrees, and the "c" by 240 degrees.

A second order Butterworth filter at twice the cutoff frequency is assumed. Such an analysis filter agressively minimizes the strengths of the fifth and seventh harmonics. 


Only a few of the results are listed in this "sampler" sequence. The full listing is available only to Synergetics partners and magic sinewave seminar participants.
