Description of the working principles and characteristics of the hand-over frequency

The frequency transformer is divided into the t-tanger and t-tanger variants, which allow the t-tanger to directly convert the t-tanger to a communication that can be controlled by the frequency and voltage, so it is called the t-tanger, which we talk about today。

The working principles of the fertilizer

The method of operation of the fertilizer is to produce the required transformer frequency power directly via several sets of phase-controlled switches, with the advantage that it is efficient, that energy can facilitate return to the grid, and that the maximum frequency of the output of its greatest disadvantage must be less than the input power frequency of one third or one half, otherwise the output wave shape is too poor and the machine is shaking to work. The turnover has so far limited its use to a low-rotation rate setting, thus significantly limiting its use。

First, because it is a direct transformation, it is more efficient than a general variable

Second, because the exchange output voltage consists directly of certain parts of the envelope of the exchange input voltage wave, the output wave shape is better when the output frequency is much lower than the input exchange power

(c) thirdly, the frequency transformer has a natural replacement of the grid over zero voltage and can use an ordinary transistor tube

Fourth, because of the characteristics of the circuit composition, the number of transistor components used is higher; fifth, the power factor is lower, especially when operating at lower speeds, and requires appropriate compensation。

Given the above characteristics, the cross-turner, especially suitable for low-speed movement of large capacity, has a wide range of applications for rolling steel, cement, tractor, etc。
