It is a modified armature circuit converter. • Output voltage UA respectively Udmax 2-Q : see table 2.2/1. • Recommendation: Field voltage 0.5 to 1.1 * UV • The three-phase field supply converters DCF 600 needs a separate active overvoltage protection unit DCF 506 for protecting the power part against too high voltages. The overvoltage protection unit DCF 506 is suitable for 2-Q converters DCF 601 and for 4-Q converters DCF 602. ⎛ 100% + TOL ⎞ U A = UV * ⎜ ⎟ * 0.9 ⎝ 100% ⎠ TOL = tolerance of line voltage in % UV = Line voltage • Recommendation: Field voltage 0.6 to 0.8 * UV DCF 504A • Fully controlled antiparallel thyristor bridges (4-Q). • With this unit fast response excitation / de-excitation and field reversal is possible. For fast response excitation an appropriate voltage reserve is necessary. In steady-state condition, the fully controlled bridge runs in half controlled mode to keep the voltage ripple as low as possible. With a fast changing field current, the bridge runs in fully controlled mode. • Same design as DCF 503A Assignment Field supply converter to Overvoltage protection unit Field supply converter for motor fields DCF60x-0025-51 ...
