Detailed Product Description

Single Phase Controlled Rectifier With RAMP Comparator Firing Scheme ST2708 is a compact, ready to use power electronics experiment board. Ramp comparator firing circuit is available on board. This trainer is helpful for students to know how to generate firing pulses for single phase converter using ramp comparator firing scheme. Synchronized sine signal converts into square wave using zero crossing detector and generates ramp signal. Ramp is compared in comparator with reference voltage and generates firing pulses. The trainer is so designed that different experiments can be performed by making connections using patch cords and observe the wave forms at different points in the circuits. Each trainer is provided with a extensive students manual which covers the related theory and step by step instructions for performing the experiments. Features Built in power supply. Easy to operate and understand. Firing circuits on single board. Gradual firing angle control upto 180 degree. Test points to observe output of different blocks. Sockets to make different connections. On board AC sources of 15 V and 18 V. On board rectifier components and load. In built pulse transformer for isolation. More than six experiments can be performed on single board. Experiment To Study the ramp comparator firing scheme. To Study the half wave controlled rectifier.
