1- AC-DC CONVERSION DL PEL201

DESCRIPTION

The DL PEL201 is a multipurpose bench to study the conversion from alternating current to direct current, using different configurations of non-controlled and controlled rectifiers, to apply these concepts later to drive AC and DC motor drives. The course is divided into two parts: the study of uncontrolled rectifiers using silicon diodes and the study of controlled rectifiers using Silicon Controlled Rectifiers (SCR). Its modular structure makes it easy to reconfigure the system to perform several experiments in various subjects, such as uncontrolled diodes and static converter circuits, thyristors, and single pulse/two-pulse midpoint converters, to name a few.    

2- AC-AC CONVERSION DL PEL202

DESCRIPTION

The DL PEL202 is a multipurpose bench to study the conversion from alternating to alternating current. Its main applications are in controlling temperature, lighting, and induction motors (with phase control, on-off control, and proportional time control). The course is divided into two sections: the first part studies thyristors and controlled AC/AC converters using power components such as diodes, SCR, and Triacs with two and six pulse control units, and the second part shows a standard application with the study of a double-time constant light dimmer circuit consisting of Triac and Diac with fault simulation. Its modular structure makes it easy to reconfigure the system to perform several experiments in various subjects such as Triac, single-phase, and three-phase controllers, to name a few.

3-CONVERSIONE DC-DC DL PEL203

DESCRIPTION

The DL PEL203 is a multipurpose bench used to study the conversion from direct current to direct current, and its main applications include DC power supplies and DC motor drives. The course is divided into two sections. The first part covers choppers and directly studies the conversion from a fixed DC input to a variable DC output using SCR, MOSFET, and IGBT. The second section studies switching mode power supplies and analyzes the properties of the PWM control using circuits as flyback and forward converters. Its modular structure makes it easy to reconfigure the system to perform several experiments in various subjects, such as step-up/step-down converters, speed control of a DC motor, and asymmetric half-bridge forward converters, to name a few.

4- DC-AC CONVERSION DL PEL204

DESCRIPTION

The DL PEL204 is a multipurpose bench used to study the conversion from direct current to alternating current and its main applications, such as AC motor drives and AC uninterruptable power supplies. The trainer is designed to study the properties of the inverter with a Pulse Width Modulation control. Its modular structure makes it easy to reconfigure the system to perform several experiments in various subjects such as a four-quadrant drive with cyclo converter, control of stator voltage with three-phase AC voltage controller, variable-frequency drive with space vector PWM (SVPWM), to name a few.

5- MOTOR DRIVES DL PEL205

DESCRIPTION

The DL PEL205 is a multipurpose bench for AC and DC motor drives where power electronics converters are studied as interfaces between input power and motors to control speed and position. The trainer is dedicated to studying different types of machine drives: DC motor drives, AC slip-ring motor drives, and AC squirrel cage motor drives, all of which have speed control. Its modular structure makes it easy to reconfigure the system to perform several experiments in various subjects, such as single-phase full-bridge DC chopper/inverter (square wave or sine wave with PWM control) and frequency converter, to name a few.

Power Electronics is the branch of Electronics that studies the devices, circuits, systems, and procedures for processing, controlling, and converting electrical energy. Technological development in solid-state electronics and the semiconductor field has transformed power electronics, providing active devices with higher switching speeds and power handling at lower costs. The power electronic devices commonly found in the industry are Diodes, SCR, TRIAC, MOSFET, and IGBT. Their different attributes dictate how they are used in different applications according to the type of input and output power: AC to DC, AC to AC, DC to DC, or DC to AC. This technology can be found in various settings impacting everyday life, from consumer electronics, industrial applications, transportation, telecommunications, and power systems to space technology.
