Power Electronics Trainers

Power electronics trainers let students switch real current and observe the waveforms that result, which is the part of the subject that cannot be learned from a simulator. Naugra Export manufactures and exports the complete range from Ambala, India.

Device characteristics

SCR characteristic trainers covering forward and reverse blocking, latching and holding current, TRIAC and DIAC characteristic trainers, UJT relaxation oscillator and firing circuit trainers, MOSFET and IGBT characteristic trainers, and gate drive and isolation trainers using pulse transformers and opto-couplers.

Converters

Single phase and three phase half and fully controlled rectifier trainers with resistive and inductive loads, dual converter trainers, AC voltage controller trainers, cycloconverter trainers, and step-up, step-down and buck-boost chopper trainers.

Inverters and drives

Single phase and three phase inverter trainers, PWM inverter trainers, series and parallel inverter trainers, DC motor speed control by chopper and by controlled rectifier, and AC motor speed control by V/f method.

Applications

SCR lamp flasher and dimmer trainers, emergency lighting and battery charger trainers, induction heating demonstration units, UPS trainers and solid state relay trainers.

Board and base unit format

Most experiment boards can be used as standalone units with an external DC supply, or plugged into a power electronics base unit that provides built-in DC and AC supplies, SCR and diode assemblies, pulse transformers, pulse amplifiers, isolation transformers, a single phase controlled rectifier firing circuit, a resistive load selector switch and potentiometers. Buying the base unit once and the boards individually is usually the cheaper route to a full syllabus.
