Peak switch current
WebThis circuit helps to mitigate the voltage spikes that occur due to ringing between the transformer’s leakage inductor and stray capacitances in the circuit at the switching node. Without the snubber, the voltage spikes add noise and can even cause MOSFET breakdown. Figure 5 shows a flyback converter with a snubber circuit. WebAug 28, 2024 · Peak current at the inductor likely cannot be measured by using a DMM, perhaps a low resistance current shunt is required series to the inductor and switch node of the IC but Im not sure on proper method. Eq 1 Duty Cycle. D = 1 - (8 * 0.7 / 25) = 0.776. Eq 2. ΔIL = (8 * 0.776) / (1.2M * 6.8u) = 0.76A.

WebEfficient power conversion requires switching periods on the order of 25 to 500 ns which produce unwanted voltage transients at the output terminals of the power supply. Further … WebPeak switch current (not your average current mode converter) Most current mode converters have a reduced peak switch current limit at high duty cycles. This is a result of …
WebHere, the peak switch current (which is also the peak inductor current) is monitored, resulting in a current waveform every half cycle. Due to the MOSFET switching, the current signal has strong switching noises. Figure 5.
