Hardware description of EVAL-M1-CTF620N3
To meet individual customer requirements and make the EVAL-M1-CTF620N3 evaluation board a basis for
development or modification, all necessary technical data like schematics, layout and components are
included in this chapter.
5.1
Inverter section using CIPOS
™
Tiny IPM
The inverter section is also implemented using the CIPOS
™
Tiny IPM as sketched in Figure 11. This advanced
IPM is a combination of Infineon’s newest low VCE(on) Trench IGBT technology optimized for best trade-off
between conduction and switching losses and the industry benchmark 3 phase high voltage, high speed driver
(3.3V compatible) in a fully isolated thermally enhanced package. A built-in high precision temperature monitor
and over-current protection feature, along with the short circuit rated IGBTs and integrated under-voltage
lockout function, deliver high level of protection and fail-safe operation. Using a dual in line package with full
transfer mold structure resolves isolation problems to heatsink. The three pairs of capacitors C20 and C25, C21
and C26, C22 and C27 are used as bootstrap capacitors to provide the necessary floating supply voltages V
BS3
,
V
BS2
and V
BS1
respectively.
