2. CURRENT MODES
(MIXED
(
SLOW
+
FAST) DECAY MODE Effect)
Current value in increasing (Sine wave)
Sine wave in decreasing (When using MIXED DECAY Mode with large attenuation ratio (MDT%) at
attenuation)
Sine wave in decreasing (When using MIXED DECAY Mode with small attenuation ratio (MDT%) at
attenuation)
If RNF, current watching point, was the set current value (output current) in the mixed decay mode and
in the fast decay mode, there is no charge mode but the slow
+
fast mode (slow to fast is at MDT) in the
next chopping cycle.
Note: The above charts are schematics. The actual current transient responses are curves.

Because current attenuates so quickly, the current
immediately follows the set current value.

Because current attenuates slowly, it takes a long time
for the current to follow the set current value (or the
current does not follow).
