The Class-I Amplifier The Class-I Amplifier I类放大器 Class-I, also known as BCA (Balanced Current Amplifier) is Crown’s patented, cutting-edge technology that gets more power out of an amplifier with less waste than was ever before possible. I类，也被称为BCA （平衡电流放大器）皇冠的专利，尖端的技术，获得了更多的放大器功率输出，减少浪费比以 前可能。 Class-I technology offers several key advantages. It provides unprecedented efficiency, requiring less power from the AC supply than other designs and that can add up to significant cost savings over the life of the amplifier. Class-I handles reactive loudspeaker loads easily and gracefully, by reusing energy returned from the loudspeaker rather than dissipating it as heat or forcing the amp into premature current limiting. This characteristic means class-I amplifiers run better and longer— especially at lower impedances. It also makes them more reliable, since they are not constantly stressed to their limits or subjected to excessive heat. Best of all, as proud owners can attest, amplifiers with class-I technology sound great, with a powerful, accurate sound that stands out from the competition. I类技术提供了一些关键的优势。它提供了前所未有的效率，需要更少的功率比其他的设计和从交流电源，可以添 加显着的成本节约的整个生命周期的放大器。I类可以轻松地处理活性扬声器负载优雅，再利用能源，返回的扬声 器而不是散热热或迫使过早电流安培的电流限制。这种特性I类放大器运行得更好和更特别在较低的阻抗。这也使 得他们更加可靠，因为他们不经常强调他们的限制或受到过多的热量。最重要的是，作为引以为傲的业主可以证明， I类放大器与技术提供了强大的，准确的声音，声音很大，脱颖而出的竞争。 Crown’s class-I “switching” technology is a completely new adaptation of switching (PWM) amplifier design. This paper provides a simplified overview of Class-I, but before we explore its inner-workings, we need to look at the foundation of all previous high-power amplifier designs in order to fully appreciate how class-I stands apart. 皇冠的I类“切换”技术是一种完全新的适应切换（PWM）放大器的设计。本文提供了一个简单的概述I类，但在我 们探讨它的内部运作，我们需要看看以前所有的高功率放大器设计的基础为了充分了解I类代表分开。 TRANSISTOR OPERATION 晶体管工作 To understand the different amplifier classes, it helps to understand a little about
