Properties of the Choke&Inductor Program
||English, French, German, Italian and Spanish
||Metric and USA units
|Power range per phase at 50/60 Hz
|| 0.1VAr...20kVAr per phase @ 50Hz
||L=U1/I1/(2 x pi x f1)
L=U1/Irms/(2 x pi x f1)
L= U x T / Ipeak
L= (U x dT - I x dL)/dI
||Max. 8 harmonics ( included DC-component)
|Wire & Foil
||Cu & Al- foil and round & flat wires, with 3
||Cold rolled, grain oriented, Ni-Fe alloys,
ferrite, amorphous and powder
||Single section bobbin, tube or insulation
without flange, open and closed
The cores and bobbins & tubes, which do not exist in the core data
pools, can be created by user.
||Potted and not potted
|Core assembly, number and position of gaps
||EI,UI,..., C-cores and modulus cores
Max 8 gaps per leg with 8 different position combinations
||One cooling channel within the winding, only in the front
and in the back of the winding and one cooling channel between the core
and the winding.
||Dry, one component varnish and 2 components
varnish, under vacuum.
||Wood, printed board, metal
|Duty cycle operation mode
||Min. time 5 seconds, with 2 times and 2 loads
|Criterion of the design:
Temperature rise in nominal and duty cycle operation: 10°K ...250°K
||Optimized in accordance with the temperature
||-100°C ... 120°C
|Core families data pool
||EI, EE,..., UI, LL,..., 3PhEI, C-cores, EC, ETD, RM, PM, P,
EFD, EPC, RS, DS, PQ,...
The cores and bobbins, which do not exist in the core data pools can be
created by user.
||In this mode the program designs in accordance with the
|Test and simulating mode
||In this mode the user can change manually the turns, wire
size, thermal and peak current, gap size and position, frequency, duty
cycle, steel,... and recalculate the choke.
||Motor filter choke
Power factor correction choke
Current compensated chokes
Common mode choke
Motor starting choke
