WebJan 23, 2024 · Transformer inrush current is defined as the maximum instantaneous current drawn by the transformer when the secondary side is unloaded or in open circuit condition. This inrush current harms the magnetic property of the core and cause an unwanted switching of transformer’s circuit breaker. WebJan 19, 2024 · I would like to implement the inrush current limiting circuit suggested by the FTDI chip, I am using. Unfortunately, my FT232RL is setup for 3.3V, so PWREN (CBUS3) is also driven with 3.3V. The MOSFET I am using has a Gate Threshold Voltage of -0.55V and therefore the MOSFET will never be turned off completely, when PWREN is high (3.3V).
WebJun 17, 2024 · This has the added advantage of acting as an input filter and reducing conducted EMI interference when used as a Pi-Filter. The inrush current is split between the supply voltage capacitor, C1, and the inductor-limited input current required by C2 and the converter (shown dotted). Fig 6. Using an input pi-filter to reduce the inrush current for ...
