In this paper, we report on the design of a digital three-phase micro-generator of voltage that is going to be part of a lab-on-chip system based on smart sensors for medical diagnosis and instrumentation. The digital generator is implemented on a field-programmable gate array (FPGA) and it will deliver three voltage waveforms with equal magnitudes and phase shifted 120° one of each other. The benefits of this power source are mainly related to the ability of balanced three phase systems to deliver constant instantaneous power to the loads, thus eliminating vibrations and other disturbances produced by oscillation in the output waveforms of typical mono phase systems. It is expected that the resulting three phase digital generator will serve as a very reliable power source for driving micromechanical actuators used in sophisticated medical applications.
