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 later apply these concepts to drive AC and DC motor drives. The course is divided in 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, single pulse/two-pulse midpoint converters, to name a few. |

AC-AC CONVERSION DL PEL202 |
DESCRIPTION The DL PEL202 is a multipurpose bench to study the conversion from alternating current to alternating current. Its main fields of applications are in the control of 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 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. |

DC-DC CONVERSION DL PEL203 |
DESCRIPTION The DL PEL203 is a multipurpose bench to study the conversion from direct current to direct current, and its main fields of applications such as DC power supplies and DC motor drives. The course is divided into two sections. The first part covers choppers and studies the conversion from fixed DC input to a variable DC output directly with the use of SCR, MOSFET and IGBT. The second section studies switching mode power supplies and analyzes the properties of the PWM control with the use of 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, asymmetric half-bridge forward converter, to name a few. |
