After using magnetic cores for a period of time, many factories may notice relatively significant losses. So why do these losses occur in related equipment, and how can we reduce them? Let’s take a closer look.

1. Causes of Losses  

Losses are generally caused by two main factors: magnetic core losses and coil losses. The extent of these losses usually depends on the circuit mode. The losses that often raise questions are primarily due to the alternating magnetic field within the relevant materials. This type of loss is essentially unavoidable, but there are ways to mitigate it.

2. Reducing Switching Frequency  

Lowering the switching frequency is a relatively effective way to reduce magnetic core losses. If the switching frequency rises to a critical value, related losses will increase. However, daily operations rarely reach this critical point, so reducing the switching frequency is a feasible approach.

3. Allowing Copper Loss  

To reduce magnetic core losses, another strategy is to manage copper losses. Changes in copper losses can influence overall losses, so observing the relationship between the two and adjusting copper losses accordingly can help minimize total losses.

It is entirely normal for magnetic cores to experience losses. However, if the losses are abnormal, equipment inspection may be necessary. For normal losses, the two methods mentioned above can help reduce them to some extent, effectively extending the equipment’s service life.
