A Subtraction Operation Converter with Multiple Outputs and Its Control Strategy

Electrolysis and electroplating require abundant voltage waveforms. Traditional electroplating converters can only provide a single output waveform. This paper presents a converter with multiple output waveforms, which can realize various required waveforms by subtraction operation. Compared with traditional converters, the proposed converter has a simple structure and is easy to control. Only one converter can realize multiple voltage waveform outputs. The proposed converter is suitable for electrolysis, electroplating and other occasions that require multiple types of output waveforms. The converter topology is analyzed theoretically, and the control strategy of the proposed converter is designed. Experimental results are provided to demonstrate the correctness and feasibility of the proposed converter and its control strategy.
