What is Soft Start Feature which Reduces Inrush Current in Inverter/UPS? A soft start feature in an inverter/UPS is a function that gradually increases the voltage and current applied to a load instead of immediately using the total voltage and current. This helps to reduce the inrush current, which can be a significant source of stress on the heavy loads and the inverter/UPS itself.
The soft start feature is typically implemented using a PWM (pulse-width modulation timer) inside the microprocessor. The PWM timer gradually increases the voltage over a while, while the PWM controller reduces the duty cycle of the output waveform. This has the effect of reducing the peak current and increasing the startup time.https://www.eaton.com/content/dam/eaton/products/backup-power-ups-surge-it-power-distribution/backup-power-ups/eaton-UPS-Fundamentals-Handbook-COR172FYA.pdf
The soft start feature can be beneficial for many reasons. It can help to protect heavy loads like fridges, motors and airconditioners etc., from damage, prolong the life of the inverter/UPS/Home UPS, and reduce the risk of electrical transients. It can also be used to prevent nuisance tripping of circuit breakers or fuses.https://suvastika.com/automatic-by-pass-feature-in-inverter-ups-home-ups/
Here are some of the benefits of using a soft start feature in an inverter:
- Reduced inrush current: The soft start feature reduces the inrush current, which can help to protect heavy loads from damage and prolong their life.
- Increased startup time: The soft start feature increases the startup time, which can help to reduce the risk of electrical transients.
- Prevents nuisance tripping: The soft start feature can help to avoid the nuisance tripping of circuit breakers or fuses.
- All our products manufactured like UPS, Inverter, Home UPS, Energy Storage Systems, Lift UPS, Online UPS etc., has this feature programmed into the microprocessor of each product to provide more power to the consumer and increase the life of the heavy loads run by our equipment.
- Soft Start Feature Reduces Inrush Current in the Inverter/UPS, which is very important for the life of the Inverter/UPS.
