Temperature rise is one of the most important thermal indicators when evaluating a high frequency transformer for switching power supplies. A transformer may meet its voltage, current, and insulation

The transformer turns ratio is a fundamental parameter used to determine the voltage relationship between the primary and secondary windings. For power supply applications, however, calculating the co

Switching frequency is one of the most important parameters in high frequency transformer design. It affects the magnetic core, number of turns, power density, core loss, winding loss, temperature ris

High frequency transformers and power transformers both transfer electrical energy between circuits, but they are designed for different operating conditions. For engineers and OEM buyers, the main qu

A high frequency transformer is one of the key magnetic components in a switching power supply. Unlike a conventional power frequency transformer, it is designed to operate at much higher switching fr

During a factory visit, a customer from Italy picked up two PCB transformers from our inspection table and asked a question we've heard many times over the years. "They're the same size,

One of our long-term customers once called us with a problem that had already delayed their production schedule for nearly two weeks. Their switching power supply would occasionally fail after several

Not long ago, an engineer from an industrial equipment manufacturer approached Wuxi Huipu Electronics Co., Ltd. with what seemed like a straightforward question. "We're redesigning one of our

One of our OEM customers once sent us two PCB transformers that looked almost identical. Both had the same footprint. Both had the same turns ratio. Both delivered the same output voltage. Yet one wor

A design engineer from a UK electronics company once shared an experience that perfectly illustrates why PCB transformers are often overlooked. His team had spent months developing a compact control b

A customer from the Netherlands once walked into our production workshop, picked up two pulse transformers from different trays and asked a question that made everyone smile. "They have exactly t

One Monday morning, we received an email from a long-term customer in Spain that simply read: "The gate driver has failed again. We've replaced the IGBTs twice, changed the controller once, a
