Similar to methods mentioned by Marco and JohnB, I am using what I call a "Floating Snubber" which returns some energy per pulse, allowing smaller, lower inductance snubber components.
This snubber is in a hobby pwm push pull 300 Watt inverter, I am working on 2 versions which both have essentially the same snubber.
https://app.box.com/s/2orjo7boyqa74c0siq88yy8ydzspus4iSnubber diodes are SB1H100, The converter link supply is 32 V DC.
The main IGBT's (obsolete IXGH32N60C) switch off with unimpeded rise to off-state until overshoot starts the snubbers.
The off rise time from about 12 Amp to peak overshoot is 70 ns and Collector Off-loss per cycle is measured at 0.93 Watt.
Collector On loss to 12 A, again not impeded by snubber, measures 0.68 Watt per cycle.
The floating snubber capacitor voltage varies depending on collector current and duty cycle, and peak voltage is set by the value of the discharge resistor.
The discharge resistor is presently of 3 Watt rating.
