Single-phase rectifier DC welding power load from road circuit
A single-phase rectifier DC welding power load from the road circuit is presented. The contactor KM utilizes a CJ20-40A model rated for 220V. An adjustment potentiometer RP is employed to ensure proper arcing, while the relay KA2 is designed for...
Antialiasing And Sync-Compensation Filter
Two dual-biquad filter chips and some external components form a multipurpose filter to reconstruct D/A converter signals. Connected to a converter's output, the filter provides antialiasing, reduces the D/A converter's quantization noise, and compensates for the "sync" function (attenuation). The...
