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 6 current and voltage out of phase
This diagram shows what happens as the voltage increases across a motor winding. The current must work harder to stay in step with it. However, despite such efforts, the current can't keep up and lags behind the voltage.
