IGBT ZVS Induction Heater?

Among the many tutorials for building an induction heater out on the internet, there are two primary types. Some heaters use a ZVS circuit, and are quite simple but generally limited to a power of around 1000 watts, not enough to melt most metals. Other heaters use PLL controllers and coupling transformers to add charge the primary coil/capacitor loop, and these can be much more powerful but are significantly more complicated (and expensive) to build. It seems the limiting factor in the power of the ZVS circuits is that they can use only 2 MOSFETs, and each must conduct large amounts of current. However, if these could be replaced with IGBTs, which could conduct far more current, a much more powerful ZVS induction heater could be built. Is there any reason IGBTs couldn't be used for a ZVS heating circuit?

Complementary transistors

What or which PNP Complementary transistor can I use with a N-Channel  IGBT HGTP10N120BN 35A 1200V NPT   Transistor  ? I really will thank you . I'm building an H- Bridge motor drive. Ed.

Variable frequency drive

Hello there instructables, I have another question discussing maglev theory and i was directed that the true way to build this project was to use 3-phase power! So this question, although related, is also an entirely new project in its own right! Now to the point, i have been researching single to 3-phase conversion, and there are a few options available like rotary or static phase converters, but i have been intruiged by a device called a variable frequency drive! Okay so what i understand so far (i think) is that these convert ac to dc, run that dc through a H bridge rectifier using igbt's and then convert the 3 outputs back to ac...... okay assuming my analogy is correct so far, to my question, 1. How are the igbt's triggered in the h bridge? do they use a function generator with altering timesteps to create the seperate phases? 2. Also how are these kept in sequence with eachother? Many thanks in advance for any help you can provide!
