产品细节：SCYC51020 电源脉冲板 一般是用在开关电源里
脉冲板一般是用在开关电源里的，他的作用其实和普通变压器是一样的，都是给交流电变压，不同的是普通变压器变压的是正弦波而脉冲变压器变压的是有一定或可调占空比的方波（可以理解为脉冲信号），常用的的PWM信号即脉宽调制信号。
至于是不是变压锯齿波我似乎听说过但没有接触过。
脉冲变压器变压的信号要比不同电源变压器的频率高的多，一般为10K–100kHZ,而普通电源变压器为50HZ。这样脉冲变压器的效率就要比普通变压器高得多，体积亦可以小很多，体积可以缩小–这就是开关电源比线性电源（普通电源变压器的电源）优越的特点之一。
把正弦波变成脉冲波输出的不是脉冲变压器而是变压器前端的控制电路。他通过把PWM信号把被滤波整流成直流的市电调制成高频的脉宽电压，通过脉冲变压器变压，然后通过滤波整流把变压后的脉宽电压变成直流

Pulse board is generally used in the switching power supply, his role is actually the same as the ordinary transformer, is to AC voltage, the difference is that the ordinary transformer voltage is sine wave and pulse transformer voltage is a certain or adjustable duty ratio of the square wave (can be understood as pulse signal), commonly used PWM signal that is pulse width modulation signal.
I seem to have heard of it but not been exposed to it.
Pulse transformer transformer signal is much higher than the frequency of different power transformers, generally 10K- 100kHZ, and the ordinary power transformer for 50HZ. So the efficiency of the pulse transformer is much higher than the ordinary transformer, the volume can also be much smaller, the volume can be reduced – this is the switching power supply than the linear power supply (ordinary power transformer power supply) one of the superior characteristics.
It is not the pulse transformer but the control circuit at the front of the transformer that turns the sine wave into the pulse wave output. He makes high-frequency pulse width voltage by filtering and recirculating the PWM signal into DC, and then converts the pulse width voltage into DC by filtering and recirculating
