Probing the Mysteries of Power Inverters: Part I

Thanks to power inverters, generating your own electricity doesn't mean you have to give up the convenience of AC living.

power inverters - Fig 5 three wave forms
The three voltage wave forms you can expect as output from a power inverter. 5A is a standard square wave. 5B is a modified square wave, which somewhat reduces the distortion between a sinusoidal wave and a square wave. 5C is a stair-step wave form that more closely approximates a sine wave; however, inverters of this type are more expensive.
