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.
[pdf] The circuit of a simple 100 watt inverter discussed in this article can be considered as the most efficient, reliable, easy to build and powerful inverter design. It will convert any 12V to 220V effectivel.
[pdf] Battery Chemistry: Consider lead-acid (affordable but shorter life) or lithium-ion (long-lasting and efficient). Make sure the battery voltage aligns with your inverter’s voltage (common options: 12V, 24V, or 48V).
