Method And System For Providing A Dc Voltage With Low Ripple By Overlaying A Plurality Of Ac Signals
An Ac-Dc Converter That Includes A Plurality Of Power Conversion Units That Overlay Their Signals To Generate A Dc Signal With Low Voltage Level, Small Voltage And Current Ripples, But High Dc Current. The Dc Signal Is Further Filtered By A Lc Low Pass Filter To Further Minimize The Ripples Before Output To The Load. In One Embodiment, The Plurality Of Power Conversion Units Is Preferably Powered By A Plurality Of Input Pulse Generators. In An Alternative Embodiment, The Power Conversion Units Is Powered By A Input Pulse Generator Circuit That Includes A Plurality Of N-Channel Mosfets Arranged In A Full Bridge Configuration Whose Gate Voltages Are Controlled By A Plurality Of Pulse Generators.

Title: Method and system for providing a DC voltage with low ripple by overlaying a plurality of AC signals
Usefulness: Method and system for providing a DC voltage with low ripple by overlaying a plurality of AC signals
Summary: Used for converting AC signals to DC signals.
Novelty: AC-DC converter, has multiple power converters, each to prepare time-varying output signal and overlaying circuit that combines time-varying output signals rectified by multiple diodes to prepare direct current signals
