Convert the output voltage of the UPS inverter into the required load line voltage, providing electrical isolation between the load and the UPS. Connect an inductive transformer to the output end of the pulse width modulated power inverter, and the integrated inductance and output capacitance combine to act as a filter, making the output voltage reach a sinusoidal waveform.
The purpose of this type of transformer is to provide electrical isolation between the load and the power supply side.
In IT distribution systems, prevent electrical shock to protect the insulation of connected equipment from damage It can also provide neutral point connection to form isolation or grounding.
There are third-order harmonics and other odd harmonics in the power network and user loads, and all harmonic voltages will generate additional harmonic current components in the isolation transformer coil. When the additional harmonic components are large enough, they will cause the isolation transformer to overload and overheat, reduce the operating life of the isolation transformer, and even burn out in a short period of time. The K-coefficient isolation transformer is based on the user's power supply quality and the harmonic components in the load, When designing, full consideration should be given to nonlinear loads and the impact of harmonics on the performance of the iron core and coil. Designed and manufactured according to American standards, it can effectively ensure the reliable operation of the isolation transformer in the UPS system.
