Single-channel system of pulse-phase control of a multi-phase reverse triac converter.
Abstract
A block diagram of a pulse-phase control system built on the single-channel principle of phase regulation with a range of gradual phase control up to 180 el is considered. hail. It is reported that the use of a special switching device allows discretely expand the phase range up to 360 e. hail; the system is designed for a reverse triac converter operating on an anchor motor. The developed system allows to obtain increased symmetry of control pulses and simplify the control system of the electric drive as a whole.
