NSWCCD

A digital-to-synchro converter (“DSC”) is a device that converts digital signals to analog signals suitable for use by a synchro device. A conventional DSC implements complex circuitry to take digital input and generate [V Sin({acute over (ω)}t) Sin(Φ)] and [V Sin({acute over (ω)}t) Cos(Φ)] analog signals, and a Scott-T transformer to transform these analog signals into [V Sin({acute over (ω)}t) Sin(Φ)], [V Sin({acute over (ω)}t) Sin(Φ+120)], and [V Sin({acute over (ω)}t) Sin(Φ+240)] analog signals. An inventive DSC, as typically embodied, implements a microcontroller to take digital input and generate [V Sin({acute over (ω)}t) Sin(Φ)] and [V Sin({acute over (ω)}t) Sin(Φ+120)] digital signals, a digital-to-analog converter to convert these digital signals to [V Sin({acute over (ω)}t) Sin(Φ)] and [V Sin({acute over (ω)}t) Sin(Φ+120)] analog signals, and a regular transformer (i.e., non-Scott-T transformer) to transform these analog signals (typically, in amplified voltage form) into [V Sin({acute over (ω)}t) Sin(Φ)], [V Sin({acute over (ω)}t) Sin(Φ+120)], and [V Sin({acute over (ω)}t) Sin(Φ+240)] analog signals. Inventive practice is accurate, versatile, and economical.
