2.2 List of parameters
Description:
Sets the enable signal for the individual bridges.
Value:
1:
Bridge 1 enabled
2:
Bridge 2 enabled
3:
All bridges enabled
4:
Bridge 3 enabled
Description:
Sets the modulator frequency.
The 100% value corresponds to the rated power unit frequency.
Description:
Activates the simultaneous step-down and step-up in the transition range between stepping-down and stepping-up.
Value:
0:
Deactivated
1:
Activated
2:
Activated with frequency derating
Description:
Sets the operating mode for the modulator switching frequency.
Value:
0:
Fixed switching frequency
1:
Variable switching frequency
Note:
For p55322 = 0:
Fixed switching frequency (according to parameter p55320).
For a fixed switching frequency, at a specific operating point (= ratio between the input and output voltages), the
maximum current ripple is obtained. The current ripple is very low at other operating points. However, the low current
ripple does not represent an advantage. A high switching frequency results in switching losses. This means a lower
device efficiency, which has a negative impact on energy efficiency and energy costs.
For p55322 = 1:
For a variable switching frequency, depending on the particular operating point, the switching frequency is reduced,
so that the maximum current ripple is obtained at all operating points. This improves the efficiency at many operating
points.
Description:
Display and connector output for the actual switching frequency of the modulator.
