Chopper, 1-phase, 3-phase inverter, 300 W (ref: EP230000)
Study of:
Serial Choppers, reversible:
-> Serial
-> Voltage reversible
-> Current reversible
-> Four quadrants
-> Overfitted double serial (+E/0/–E)
1-phase inverter:
-> Schift control full wave,
-> adjustable frequency: PWM +E/-E and +E/0/-E,
-> constant U/F ratio.
3-phase inverter:
-> Schift control full wave,
-> adjustable frequency: PWM +E/-E and +E/0/-E,
-> constant U/F ratio.
Important:
EP230 has been concieved to work with LV environment (Low voltage : 340 Vdc Max).
It is to be used for practical works or during a lecture course (with a computer and projector).
Optional extra:
-> D_CCA, speed and position control (depending of the operative part),
-> EP230800, D_Scil : Module for prototyping with Scilab/XCOS, generation of real time new correctors.
Technical characteristics :
EP230000 can be used with a lot of motors.
It has been conceived to help the students’ understanding in electrotechnics and power electonics, even in speed and postion control for DC or AC motors
Study of :
Allowable voltage: 60 VDC to 340V DC
-> Peak current in each static switch: 2 A
-> Frequency: from 1 Hz to 20 kHz
-> Adjustable run-up slope
-> Duty ratio adjustable between 0 and 100 %.
-> Adjustable idle time
The control and acquisiton program helps the use and understanding of the mains principles of static converters.
Optional extras:
D_CCA, program for the study of speed and/of position control,
D_Scil, program for prototyping and new correcters design.-
