Simple sine-wave generators can offer varying degrees of performance, but you’ll find it difficult to maintain a low THD with constant amplitude if the sine-wave output must remain locked to a ...

The circuit in Figure 1 can synchronize a sine-wave output through three decades of frequency—20 Hz to 20 kHz—and maintain low THD and constant amplitude . The synchronizer IC, an NXP Semiconductors ...

I have just discovered that Apex Microtechnology of Arizona actually makes a chip, the SWR200 Precision Sine Wave Reference, to do much the same thing, a nice low-distortion sine wave with a ...

One application I recently dealt with needed multiple phases of sine waves, all of equal amplitude. I considered 45°, 60°, and 90° differences, but decided 60° was the best solution.

We all know that electric utilities in the United States generate electricity at various 60-Hz voltage levels that result in a sine wave waveform. The height, or amplitude, of this sine wave is called ...

A simple mounting scheme and high reliability lend to the low cost of ownership. The AEP-5000 series is part of the full line of rugged, pure sine wave inverters from Schaefer, which includes ...

Tripp Lite SmartPro Line-Interactive Sine Wave UPS (SMC1000T) review: High-end UPS, relatively low-end price This uninterruptible power supply is a great investment for anyone looking to protect a ...

Schaefer introduces the AEP-5000 series of 5,000W, rugged, high-efficiency, pure sine wave inverters. The ‘clean’ pure sine wave output of the AEP-5000 series with less than 3% total harmonic ...
