25Hz frequency power supply, also known as crossover railway 25Hz power supply, mainly used in electric railway. With the rapid development of power electronics and microelectronics technology, the 25H think high frequency power supply, the direction of development of modular, conventional 25Hz power divider Tian-shaped core use, the use of ferromagnetic resonance principle produce 25Hz AC, although this traditional power with high reliability, but there are many shortcomings, mainly bulky, low frequency, start big impact, 25Hz waveform distortion . great new crossover 25Hz power supply with AC-DC conversion and pulse width modulation technology, with small, high frequency, waveform distortion, etc. technical parameters are as follows:
