At present, the cooling technologies of inverters include natural cooling, forced air cooling, and liquid cooling. The main application forms are natural cooling and forced air cooling. 1. Natural heat dissipation: Nat.
[pdf] The high-frequency inverter first uses high-frequency DC/DC conversion technology to invert low-voltage direct current into high-frequency and low-voltage alternating current; then, after being boosted by a high-frequency transformer, it is rectified by a high-frequency rectifier filter circuit to usually above 300V High-voltage DC power; finally, 220V power frequency AC power is obtained through the power frequency inverter circuit for the load.
[pdf] This article presents the first kW-Class, 3-phase GaN-based inverter. Hard-switched at 100-kHz PWM, its heart is a 6-in-1 power module with 600-V GaN power HEMTs, achieving a new efficiency of 98.5%, a more than 2% improvement.
