Soft starters help in reducing voltage flicker by gradually increasing the voltage to a motor during startup, which minimizes sudden and significant electrical demands on the power supply. Here’s how they achieve this:
- Reduced Inrush Current: Soft starters reduce the inrush current associated with motor startups, preventing large voltage drops that can cause flickering lights. By reducing this inrush, the voltage fluctuations are minimized, leading to a more stable power supply.
- Smooth Startup: These devices ensure a smooth start by gradually ramping up the voltage to the motor. This approach reduces mechanical stress and prevents sudden electrical surges that can contribute to flicker.
- Stabilization of Power Supply: By limiting the starting current, soft starters help stabilize the power supply, reducing transient voltage drops that can lead to flicker. This is particularly beneficial in applications where consistent lighting is crucial.
- Prevention of Power Spikes: Soft starters eliminate or reduce damaging power spikes that can cause overheating, brownouts, and flickering lights by introducing power gradually.
Overall, the primary function of soft starters is to provide a controlled and gentle startup for motors, which in turn helps mitigate voltage fluctuations and flicker effects in electrical systems.
