Medium voltage, medium frequency transformers (MFTs) are much smaller in size and weight compared to conventional low frequency transformers. The MFTs are very attractive for applications where full control of the power flow and high power density are required, such as power electronic interface in smart grids and traction converter system.
The transformer is required to withstand at least 15 kV high frequency voltage insulation continuously. Transformer magnetic core materials were reviewed and compared. Winding layout alternatives for leakage, magnetizing inductance and insulation were compared.

The instantaneous chopping of the current to zero results in very high di/dt, producing a high frequency high voltage transient as shown in Fig. 1D. Due to the instantaneous chopping of the current, the resulting voltage excursions can produce flashover of the transformer bushing and / .
3. When the secondary high voltage output of the transformer is not connected to the high voltage rectifier diode and capacitor, the output is high frequency and high voltage electricity.
A high frequency model of transformer winding is used to analyze the voltage oscillations due to various excitations such as the very fast transient overvoltage which occurs at the time of disconnecting switch operations.

Most of what is defined as High Frequency Noise typically falls into the 100KHz to 100MHz frequency range. The source of this noise in most facilities is switch mode power supplies, electronic lighting ballasts, photo copiers, and laser printers.
The problems of high power convertor and high frequency high voltage have been solved by nanocrystalline high frequency high voltage transformer and selfdeveloped large current high frequency high voltage silicon rectifier stack.
sources (< 250W), To produce high voltage source for CRTs, To produce high voltage for Xenon flash lamps, lasers, photocopies, Isolated driver circuits. The commonly used flyback converter requires a single controllable switch like MOSFET the usual switching frequency is in the range of 100 KHz.
Sustained Low Frequency Testing Procedure. N. B. : The transformer used for producing extra high voltage in this type of high voltage testing procedure, may not be of high power rating. Although although the output voltage is very high, but maximum current is limited to 1A in this transformer. Sometimes, cascaded transformers are used to get very high voltage, if required.

In a highfrequency/SMPS inverter, the ferrite transformer is used in the stepup/boost stage where the low voltage DC from the battery is stepped up to high voltage DC. In this situation, there are really only two choices when selecting topology – pushpull and fullbridge.
The highfrequency transformer is the key element for the DC/DC converter. Then, the paper focuses on highfrequency transformer design to realize highvoltage insulation, high efficiency, and high density at the same time.
