Frequency applications

For a fast IGBT suitable for high frequency applications, the typical collector current vs.

maximum operating frequency curve is reported. That frequency is defined as follows:

fMAX = (PD - PC) / (EON + EOFF)

●

The maximum power dissipation is limited by maximum junction to case thermal

resistance:

Equation 1

PD = ΔT / RTHJ-C

considering

ΔT = TJ - TC = 125 °C- 75 °C = 50°C

●

The conduction losses are:

Equation 2

PC = IC * VCE(SAT) * δ

with 50% of duty cycle, VCESAT typical value @125°C.

●

Power dissipation during ON & OFF commutations is due to the switching frequency:

Equation 3

PSW = (EON + EOFF) * freq.

Typical values @ 125°C for switching losses are used (test conditions: VCE = 480V,

VGE=15V, RG = 10 Ohm). Furthermore, diode recovery energy is included in the EON (see

Note 1), while the tail of the collector current is included in the EOFF measurements.
