Bench for the study of inverters 0.5 kW mini:

Bench allowing a study of the frequency converters according to the two control laws: an MLI control (U / f = cte); And with vector control The bench shall contain at least the following elements:

. A pulse width modulator for studying the MLI technique for controlling frequency converters, which comprises comparing a selectable reference voltage (continuous variable, rectangular or sinusoidal) with a triangular voltage of frequency multiple to that of the frequency converter Reference voltage (form and amplitude), either a pulsed current with an adjustable duty cycle or an adjustable direct current or a sine current must be obtained. The module must have selectors to select the shape and amplitude of the reference voltage and vary the load parameters (R, L), 4 mm safety sockets and a clear diagram illustrating the connection diagrams

. A power element based on IGBT transistors for three-phase machines with a minimum power of 0.5 kW, which can be operated as desired, with MLI control elements and vector control. It must contain at least:

 . A rectifier and a filter capacitor for obtaining a DC voltage;

. A brake chopper integrated in the intermediate circuit and selectable; . LEDs to indicate the presence of voltage, overcurrent, overvoltage or undervoltage, temperature, …

. Measuring points for the output voltages and currents, the intermediate circuit and the control signals, which must be separated glacially from the power element and the control element, onto 4 mm safety sockets

. A control element using the vector vector control technique to be connected to the power element already requested. It must have the following minimum characteristics:

. PI controller for speed control,

 . Galvanic separation from the power element, . Internal or external analog control of the setpoint value for the rotational speed,

 . Input and output for speed sensor (incremental type or encoder),

. Programmable analog and digital outputs and inputs,

. At least 1 relay outputs,

Bench for the study of inverters 0.5 kW mini:

The modules of the bench must be delivered complete with:

. Specific cables for electrically connecting the control module with the power module,

. Specific connecting cables and cables with motor,

. Interfacing cable with PC;

. Connecting cables for motor,

. An asynchronous cage motor for vector control, equipped with an incremental encoder or encoder, of power suitable to the power element,
