NettetA special type of inrush current limiter is a PTC thermistor, also called a resistive solid-state fuse. It provides a specified resistance over a wide voltage and temperature range until a transition temperature is reached (typically around 120°C). The PTC thermistor then tends to an extremely high resistance, essentially opening the circuit.

NettetThermistor inrush current limiters are essential and necessary to avoid current surges in the power generated in green energy systems by wind turbines, inverters, and … Nettet18. mar. 2016 · In that case, you may need some expert assistance. The use of that function should not raise a concern for excessive starting current. Edit: VFDs have a capacitor charging inrush current that occur only when power is first applied to the VFD. All VFDs must limit that inrush to prevent damage to the diodes and DC bus capacitors.

Nettet30. aug. 2024 · To limit inrush current, an NTC thermistor is placed between the power supply and system (see Figure 1). Upon power on, the NTC thermistor provides high resistance to limit inrush current. As the inrush current drops, the NTC thermistor self-heats and its resistance drops to a low enough value to pass current through. NettetNTC thermistors are specially developed to limit the current at turn-on by their relatively high resistance when they are cold. When the NTC thermistor heats up as a result of the current load its resistance decreases by a factor of 10 to 50, and the power it draws reduces accordingly. NTC thermistors are able to handle higher inrush currents ...
