very low conducted and radiated interference by optimized filtering.

COMPARISON WITH CONVENTIONAL POWER SUPPLIES

The new MS power supplies use high frequency energy conversion and regulation, which means a considerable size and weight reduction of transformer and capacitors. They also offer a large improvement of efficiency. Another advantage is a larger allowed AC input voltage variation. A disadvantage of the switching regulator, compared with the series pass regulator, is a worse specification of regulation, ripple and recovery time. However for many application. tf'"." specifications are still
suff icient.

CONSTANT VOLTAGE/CONSTANT CURRENT REGULATION

CV/CC ioad characteristrc

The MS and MST power supplies can be used either as a constant voltage source with a limited current or as a consiant current source with a limited open voltaqe. The change of mode occurs sharply at the crossing of the voltage and current setting.

Extension of the regulating loop

Regulated power supplies, as feedback controlled devices, are de signed to control the e1e ctrical parameter s of voltage or current. The regulating loop can also be extended to include a variety of physical elernents such as position, speed, ternperaturer pressure, chernical activity and the like. Assurning the necessary transducers and sensors, servo-like control rnechanislr's can easily be constructed using D-C regulators as translators, sulTtlrlers, arnplifiers, followers.
