Figure 4 demonstrates drain current waveforms of the
MOSFETs during turn-on, where a considerable mismatch
between drain currents is observed. The difference is not
only in the peak current of the MOSFETs but also exists in
their rising slope. This will increase both switching losses
and switching stresses on the MOSFET with smaller inductance at the source terminal, and eventually that MOSFET
will fail before the rest.
Slower switching observed from Q 1 is due to the fact
that higher inductance at its source causes a higher
transient voltage across it [V1 in Figure 1(a)], delaying
the time to reach a fully on state for the MOSFET. A
similar imbalance in drain currents exists during turnoff, causing difference in turn-off currents and losses
among the MOSFETs.
Experimental Validation of the Proposed Technique
In this section, a prototype is implemented using a total of
three Si MOSFETs in parallel. Based on the tests on the prototype, validity of the proposed approach is proven. Next, a
high-speed, high-current solid-state relay is applied using a
total of 14 Si MOSFETs in parallel for use in an energy-storage application.
Proof of Concept at Low Currents
Table 1 demonstrates the design/test parameters for the
setup implemented as proof of concept. As shown in
Table 1, a total of three Si MOSFETs (part number
IPT020N10N3ATMA1) from Infineon rated at 100 V, 300 A
are used in parallel. Shunt resistors are used in series with
each MOSFET so that its drain current can be measured.
