Headline Hengda Electronics teaches you to distinguish between good and bad power amplifier transformer cores
The quality of the core of the power amplifier transformer directly affects the quality of the power amplifier transformer, but also affects the sound quality of an audio power amplifier. Are you worried about how to distinguish between high quality and low quality iron cores? Today Hengda Electronics leads everyone and understands it thoroughly. 【see details】

  • 变压器的漏磁

    Magnetic leakage of transformer

    In the transformer, if the primary magnetic flux is not all the turns of the secondary, leakage inductance is generated. Leakage inductance is a parasitic parameter. Taking a single converter as an example, when the switch changes from the on-state to the off-state, the energy stored in the leakage inductance is released, and sometimes a large spike voltage is generated, causing ...

  • 设计变压器时所需要的技术参数

    Technical parameters required when designing a transformer

    Designing a transformer is a multi-faceted process that not only meets the requirements of customers, but also is cost-effective. Therefore, manufacturers need to know some necessary technical parameters when designing products. Let me tell you what you need to provide. 【Learn more】
  • 同等功率的环形变压器体积是否越大越好

    Is the volume of the toroidal transformer of the same power larger?

    People who do n’t know enough about transformers will think that the bigger the transformer, the better. In fact, this concept is wrong. 【Learn more】
  • 恒达为您解答低频变压器该如何选择

    Hengda answers how to choose a low frequency transformer

    Regarding low-frequency transformers, everyone must know its role. Its role is to propagate signal voltage and signal power. Not only that, it can also provide impedance matching between circuits, so that the direct current has an isolation effect. Of course, everyone knows high-frequency transformers ... [Learn more]
  • 恒达变压器上面VH3.96端子与CH3.96端子的区别

    Difference between VH3.96 terminal and CH3.96 terminal on Hengda transformer

    There are many types of transformer terminals, VH3.96 and CH3.96l are commonly used. And what is the difference between the two, let me distinguish it for everyone. 1. Differences in terminal shape: 2. Differences in supporting plastic shells: [Learn more]
  • 如何更好的选择环形变压器的体积

    How to better choose the size of the toroidal transformer

    For power frequency transformers, the volume of the transformer is directly proportional to the power of the transformer. The larger the power, the larger the volume of the transformer. The volume of the toroidal transformer is mainly reflected in three aspects: 1: outer diameter; 2: height; 3: inner diameter. Conventional base ... [Learn more]
  • 环形变压器噪音产生的原因

    Causes of Toroidal Transformer Noise

    Toroidal transformers produce large or small noises under normal energizing conditions. This noise is mainly caused by magnetostriction and vibration. Specifically, transformer noise has two sound sources, one is the iron core and the other is the winding. 【Learn more】
  • 恒牛功放环形变压器频频收到客户好评

    Hengniu power amplifier toroidal transformer frequently received praise from customers

    Why do more audio amplifiers use toroidal transformers? That's because the use of toroidal transformers in audio amplifiers has many advantages. Toroidal transformer is also known as ring cow. Its characteristics are convenient installation, high conversion efficiency, small magnetic leakage, and evenly and tightly winding the toroidal iron core. [Learn more]
