Abstract— This paper introduces a new dc-dc converter suitable for operation at very high frequencies under on-off control. The converter power stage is based on a resonant inverter (the Φ2 inverter) providing low switch voltage stress and fast settling time.
[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] 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).
