Low-cost high-voltage arbitrary waveform generator for broad lifetime measurements of electroluminescent devices
2016
A system for the excitation of numerous capacitive loads such as electroluminescent devices is presented. It is based on a controller equipped with up to 16 driver boards which are based on an arbitrary waveform generator. Besides the three template waveforms, any requested waveform can be generated by a Digital-to-analog converter whose output is amplified. Signals can be generated with up to 400 V pp , 500 mA and 5 kHz. Costs are kept at a minimum to enable mass production.
