The STGW35HF60WD on the test bench

A DC-DC boost converter (Figure 5) has been used as a test vehicle to evaluate two

STGW35HF60WD IGBTs working in parallel.

Boost specifications:

–Fsw = 30 kHz

–

Duty = 0.33%

–

CCM operation

A preliminary analysis has been performed to measure the dynamic

∆IC established

between several couples of paralleled IGBTs. To target the best current sharing, the static

population (as illustrated in Figure 6) and three sets of tests are reported in this document.
