| Abstract |
This paper presents single-axis digital-control servo systems for brush and brushless DC permanent magnet motors rated between 0.5 and 5kW and supplied from the 220 / 240Vac mains. The dedicated digital controller hardware and sample-data based position control software are outlined. The developed servo systems utilize a novel delta modulation based velocity servo controller. The power stage is composed of novel MOSFET bridge-leg modules switching at ultra-sonic frequencies. These custom-power-hybrid (CPH) modules are cost-effective and compact. The gate drive, isolation and protection circuitry for each MOSFET switch as well as the free-wheeling diodes are incorporated within the CPH module. |
