This board is a power frequency pure sine wave inverter mainboard. A corresponding current air switch needs to be connected in series at the input end to ensure that the positive and negative terminals of the input and other circuits are not connected incorrectly or missed before power-on

When choosing a transformer, please distinguish the type of transformer it is. Not all transformers can be used. Only compliant transformers should be used. Those with high leakage inductance and large no-load capacity should not be used. For toroidal transformers, the no-load current at the high-voltage end is below 0.1A, and for E-type and V-type transformers, it is below 0.3A at the high-voltage end. If the no-load current is too large or the leakage inductance is too high, the transformer will burn out when used

For toroidal transformers, inductors must be connected in series on one side of the low-voltage end of the transformer. For 12V/24V, 15-24uH inductors should be used, and for higher voltage inputs, 47uH inductors should be used! The EI type can be added or not depending on the situation. If the no-load current is small, it can be omitted!

This board is fully equipped with various protections, featuring low no-load current and high efficiency! The driver uses an optocoupler isolated driver board. The driver is equipped with a high-power totem tube, which makes the driving capability stronger and more stable, ensuring uniform heat distribution on the left and right bridge arms of the H-bridge. Generally, for those with not too many power tubes, there is no need to add an additional driver tube! The motherboard is approximately 10*10*6cm in size
