The transformer is suitable according to its own needs. Generally, the power of 10W is required to be greater than 15W. It is more suitable to use 150W for 150W output, which needs to be larger than the actual power.

1. The leakage inductance transformer can not be used for this board, such as microwave oven transformer, paging station, transformer on the transmitting platform. There are several silicon steel sheets inserted between the two primary and secondary tubes of this type of transformer, and no-load current, power consumption. Very high.

2. The transformer that is self-wrapping is not suitable for this board. Most of the transformers wound by the friends themselves are less than the standard because of the number of turns. As a result, after the drive board is connected, the no-load current is huge and the drive board is burned out.

3. This board is strictly forbidden to connect with high frequency transformer, otherwise the drive board will be damaged.

The no-load output voltage depends on the transformer's transformation ratio and the input battery voltage. If the no-load is normal, the load is seriously reduced. Generally, the power of the transformer is not enough. The power here is not enough. The transformer itself is a small-power transformer, and High-power multi-winding transformer, choose 12V of it, because the transformer manufacturer does it according to the total power distribution. For example: a 500W transformer with dual 28V winding, 9V winding, and dual 12V winding The manufacturer may allocate the main 400W to the double 28V winding, and the remaining 100W is given to the 9V winding and the dual 12V. At this time, the inverter is used with 12V, which can not exert the high power at all. Even 100W is impossible. The load should also be considered whether the input wire is too thin, the battery is too small, and so on. Small batteries, thin wires, and small transformers cannot use the power of the board. The transformer ratio also affects the output voltage. At this time, the most obvious is the low no-load voltage. For example, a 220V dual 17V black and white TV transformer is used. At this time, only 155V can be output.
