Abstract
ABSTRACT Conventional supply systems of electrical curtains for dielectrophoretic applications generally use as many frequency generators in combination with as many linear high-voltage amplifiers. This paper aims to develop an ‘all-in-one’ compact power supply instead of the conventional supply system. The developed three-phase power supply delivers a voltage up to 1000 V with a variable frequency. The power supply includes a 1 kV DC/HVDC converter, which is then converted into three rectangular shape voltages with a phase shift of 120°. The developed supply was successfully tested and compared with the conventional supply system for the displacement of micronised plastic particles.
