Has anyone explored using a combination of Peltier cooling and thermoelectric generation to reduce the size and improve the efficiency of switching power converters?

I'm researching alternative thermal management techniques for compact power converter designs. The idea is to use a Peltier module for active cooling, while capturing waste heat on the hot side with a thermoelectric generator (TEG), aiming to:

• Minimize or eliminate the need for a large heatsink
• Recover part of the energy used for cooling
• Reduce overall thermal losses and system size

Has anyone attempted or modeled such a hybrid system? I’m particularly interested in:

• Efficiency trade-offs and net power gain/loss
• Feasibility for low-to-mid power converters (e.g.,
