Recommended Operating Conditions
Note:
(1) It is recommended the bootstrap diode D
1
to have soft and fast recovery characteristics with 600-V rating
(2) Parameters for bootsrap circuit elements are dependent on PWM algorithm. For 15 kHz of switching frequency, typical example of parameters is shown above.
(3) RC coupling(R
and C
) at each input (indicated as dotted lines) may be used to prevent improper input signal due to surge noise. Signal input of SPM is compatible with stan-
dard CMOS or LSTTL outptus.
(4) Bold lines should be short and thick in PCB pattern to have small stray inductance of circuit, which results in the reduction of surge voltage. Bypass capacitors such as C
1
, C
2
and C
3
should have good high-frequency characteristics to absorb high-frequency ripple current.

Note:
Attach the thermocouple on top of the heatsink-side of SPM (between SPM and heatsink if applied) to get the correct temperature measurement.
