Deriving photovoltaic-inverters from industrial inverter technology above 100kW under the consideration of an existing technology followed by an economic analysis and market chances

Abstract

The Master Thesis should give a support and incentives for market entry and a development for PV Inverter Technology in the high power range for industry drive-inverter manufacturers. Drives and inverters are located in the field of power electronics. Drives are used in the industry mainly for speed regulation of asynchronous AC motors in million pieces a year. PV inverters are used to convert unstable DC power from distributed energy resources to stable AC grid adequate power quality. Till yet the market is shared between inverters and drives, with the exception of some companies in the view of drive manufacturers. The main question of the Master Thesis is, if there is a market for high power PV inverters derived from industrial drives. Drive inverters, which are well positioned in the industry since several years, in principal have the same technology as PV inverters. High quality, large quantity, harmonic compensation, field approved, are only some of the main features where drives are well approved over a long period on the global market. The focus will be on market chances followed by price analyses and technology requirements.
