Three Phase Half Controlled Thyristorized Bridge Converter
Product Code : JA-PET-1413
The three phase half controlled thyristorized bridge converter is a power electronics trainer board for studying line-commutated, half-controlled three-phase rectification in engineering and polytechnic laboratories. It combines the converter with a firing card for each phase, R and R-L loads, a freewheeling diode and two digital panel meters, so students can observe control signals and output waveforms and measure load voltage and current. It runs on 3-phase 415 V, 50 Hz mains (SKU JA-PET-1413).
