Have you been bothered by how to pick a buffer assembly? Calculating how much capacitance and resistance to add is a challenging task. Here is a shortcut to solve this problem. Figure 1 shows the power stage of the forward converter. The converter is operated by a transformer that couples the input voltage to a secondary circuit that is then rectified and filtered by the secondary circuit. The reflected main voltage and the transformer leakage inductance form a low impedance circuit. When D2 is forced to commutate off through such a resistor, a buffer is usually required. D2 can be a silicon pn diode with a reverse recovery charge that must be depleted before it is turned off. This loads up the excess current in the leakage inductance, resulting in high frequency ringing and excessive diode voltage. A similar situation exists for Schottky diodes and synchronous rectifiers, the former because of its large junction capacitance and the latter because of its turn-off delay time. KNB1-32 Miniature Circuit Breaker
KNB1-32 Mini Circuit breakers, also named as the air switch which have a short for arc extinguishing device. It is a switch role, and also is a automatic protection of low-voltage electrical distribution. Its role is equivalent to the combination of switch. Fuse. Thermal Relay and other electrical components. It mainly used for short circuit and overload protection. Generally, According to the poles, mini Circuit breaker can be divided into 1P , 1P+N , 2P, 3P and 4P.
