Executive Summary - Perfect Power

— a measure of the purity of the electric waveform on powerlines. A power quality event, which is not the same as an outage, occurs when one of the waveforms differs from a pure sinusoidal waveform or one or two phases of power are lost. Measurements that can quantify power quality are harmonic distortion and peak-to-peak voltage.

Electrical: Power Quality - A Power Quality Primer

The power supply was heavy, bulky, and fairly inefficient. Recently (in the last ten years or so), partly because of the need for lighter weight and higher efficiency, the "switched-mode" power supply was developed. The switched-mode power supply has a full-wave bridge rectifier (BR1 in diagram) directly connected to the incoming 120 V AC line.
