Direct Current Direct Current Conversion

Model No. DL PEL203

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 analyze 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, and asymmetric half-bridge forward converters, to name a few.
