Students use hardware from the Integrator add-on board combined with NI ELVIS and LabVIEW software to generate a fully functional solution for teaching power electronics to students.

Labs for Integrator Power Electronics Add-On Board

by Integrator Ltd.

In these labs, students will build and interface with power electronics circuitry to experimentally learn the fundamentals. The Integrator Power Electronics Add-On Board provides a hands-on platform for teaching concepts in power electronics including transformers, rectifiers, and voltage regulators with 14 different circuits. The student is guided with step-by-step instructions to each of the 19 included labs and will use the educational board for hands-on experiments with the electric circuits, connect various power sources and meters, and conduct experiments with the studied circuits. The student will collect, display, and analyze data to come to conclusions about power electronics functions. With this add-on board, students can learn the operating principles of voltage and current regulators, converters, AC voltage and current generators, transformers, rectifiers, diodes, Zener diodes, silicon-controlled rectifiers (SCRs), and more.

DC VOLTAGE SOURCES

Students determine experimentally the internal resistance of a voltage source and plot its external characteristic graph.

AC VOLTAGE SOURCES

Students determine experimentally the internal impedance of an AC voltage source and plot its external characteristic graph.

DC CURRENT SOURCES

Students determine experimentally the internal resistance of a DC current source and plot its external characteristic graph.

LINEAR VOLTAGE REGULATORS (VOLTAGE INSTABILITY BY CURRENT)

Students experimentally determine the regulator’s voltage instability by output current.

LINEAR VOLTAGE REGULATORS (VOLTAGE INSTABILITY)

Students determine experimentally the voltage instability ratio of a linear voltage regulator.

SWITCHING VOLTAGE REGULATORS

Students plot the graph of a switching regulator’s output voltage on PWM (Pulse Width Modulator) duty factor.

SWITCHING VOLTAGE REGULATOR WITH FILTER

Students plot the loading characteristic and the dependence of output voltage on the duty factor for a switching voltage regulator with filters and determine the voltage ripple factor depending on filter parameters.

SILICON CONTROLLED RECTIFIERS

The objective of this lab is to plot the current-voltage characteristic of a Silicon Controlled Rectifier (SCR) and determining their following parameters (Gate trigger current, holding current, trigger voltage).

ZENER DIODES

Students determine the Zener voltage, stabilization error, and minimum stabilization current of a zener diode.

SINGLE-PHASE TRANSFORMERS IN OPEN-CIRCUIT AND SHORT-CIRCUIT MODES

Students determine the equivalent circuit parameters of a transformer by measuring the voltages and currents in the primary and secondary windings in open circuit and short circuit modes. The full impedances of the primary and secondary windings are to be calculated along with the coupling factor and turn ratio, then parameters of the equivalent circuit are determined.

SINGLE-PHASE TRANSFORMERS WITH ACTIVE LOAD

Students obtain the loading characteristic of a transformer. Currents and voltages of the primary and secondary windings are measured when a resistance loads the secondary. The efficiency and power factor of a transformer operating as a source of AC voltage are determined based on measurement results and its external characteristic is plotted in the lower part of the Front Panel.

SINGLE-PHASE RECTIFIERS WITHOUT A FILTER

Students experimentally determine the efficiency and ripple factor, and obtain the external characteristic for a single-phase bridge rectifier supplied from a transformer.

NON-CONTROLLED SINGLE-PHASE RECTIFIER WITH FILTER

Students experimentally determine the efficiency and ripple factor, and obtain the external characteristic for a single-phase bridge rectifier with different filters (L, C, LC) supplied from a transformer.

THREE-PHASE NETWORKS WITH TRANSFORMERS (STAR/ DELTA CONNECTIONS)

Students measure the voltages and currents in a three-phase network for the Star connection of the primary and Delta connection of the secondary winding of the transformer.

THREE-PHASE NETWORKS WITH TRANSFORMERS (STAR/ STAR CONNECTION)

Students measure the voltages and currents in the circuits of a three-phase network for Star-Star connection of the primary and secondary windings of a three-phase transformer.

SINGLE-PHASE CONTROLLED RECTIFIER UNDER ACTIVE LOAD

Students obtain experimentally the control characteristic of a single-phase rectifier and the output voltage for an arbitrary firing angle. Study the output voltage graph vs. firing angle.

THREE-PHASE CONTROLLED RECTIFIERS UNDER ACTIVE LOAD

Students experimentally determine a three-phase controlled bridge rectifier control characteristic and calculate its output voltage for an arbitrary firing angle. Study the output voltage graph vs. firing angle.

THREE-PHASE CIRCUITS WITH STAR CONNECTION OF POWER CONSUMERS

Students measure the voltages and currents in three-phase circuits for Star connection of the consumer. Different connection types are considered: symmetrical, unsymmetrical, with broken neutral line, with unbalanced loads in the star’s legs.

THREE-PHASE CIRCUITS WITH DELTA CONNECTION OF POWER CONSUMERS

Students measure the voltages and currents in three-phase circuits for Delta connection of the consumer. Symmetrical, unsymmetrical connections are considered for a broken circuit in one of the linear currents.
