Abstract :
Environmentally friendly control of organic and inorganic fouling of machinery and piping systems is a pressing challenge for both military and civilian institutions, such as the US Navy and the electric power industry. In proof-of-principal testing, pulsed acoustics based on pulsed power modulators has proven effective for both cleaning and prevention of fouling, but now commercially viable equipment is in demand. This paper describes an all solid-state modulator based on the EUPEC FZ800R33KF1 3.3-kV Insulated Gate Bipolar Transistor (IGBT) module for creating kilovolt and kiloamp electrical pulses with the appropriate microsecond resonant waveform for generating high-intensity electrohydraulic shockwaves in water at high repetition rate. The compact field-portable design will be utilized in application field testing at a US Navy test site.
