| 1. | The voltage - stabilizing step is now focused on the control of constant - power in the semiconductor laser . in fact , the output voltage is changed when the load changed . as a result , it comes to be an important technology to make it stable when the load changed 但事实证明,随着负载的变化,光电转换电源输出端的电压是不稳定的,因而采用何种方法确保在负载变化的情况下电源输出仍是稳定的就成了光电转换电源研究的一个重要问题。 |
