For 110V to 220V voltage converter, how to calculate the copper wire turns of voltage converter primary and secondary winding, how to choose the size of silicon steel sheet, and how to calculate the diameter of copper wire?

Step up and step down voltage converter will have a temperature rise during normal running. The material has good heat dissipation performance, which can quickly dissipate the heat to let the temperature stay in normal range. Of course, the premise is that raw materials of your voltage converter are in high and stable quality. If you buy an inferior voltage converter, then the problem could be serious.

Most Voltage converters on the market are safety isolation transformers removed from the industrial or ship, it was known as safety isolation voltage converter. It is safe because even if the voltage converter output voltage is 220 volts or higher, when you touch the line (even your feet without shoes) you will not be shocked. But when you touch two lines at the same time you will be shocked. This voltage converter is primary voltage through magnetic field induced to the secondary voltage and then into 220 volts (higher or lower voltage) output. Two voltage input lines and two voltage output lines of the isolation transformer is non-conductive with a multimeter, so you will not be shocked when touch one line. Even if the isolated-type voltage converter is burned, your speakers will be safe, because the primary and secondary voltage can't enter your speakers. The power of isolated-type voltage converter is relatively pure (isolated with main electric). The converter inside our audio products is like this, but the output voltage is lower. In the case, isolated-type voltage converter has much higher voltage than auto-type. A person can't lift a 2KW isolated-type voltage converter, but can carry auto-type ones.

Voltage converter and power converter reads familiar, but users are easy to confuse them. Power converter, also known as AC adapter, is a kind of transformer. Due to the power environment and civil voltage of countries and regions in the world is different, the voltage range applicable to each country appliances is different. 220V and 110V are the two kinds of common voltage. According to this, power converter and voltage converter is actually one kind of product. The usage of voltage converter is also voltage conversion, commonly 220V to 110V and 110V to 220V.

Travel voltage converter

• Travel voltage converter can convert voltage between countries.
• Voltage converter can change the voltage, like 110V to 220V, or other voltages used around the world.
• In addition of switching voltage, travel voltage converters also can be a travel adapter, because most of them can be adapted in the socket outlet of other countries.
• Usually, travel voltage converters are more expensive than the travel power adapter.
