一种可控相位的纹波产生器
摘要：
本发明涉及一种可控相位的纹波产生器，解决传统的电容检测仪器检测方法复杂、成本高的问题。本装置采用220V市政电源，电源输出连接测试主电路和控制电路，测试主电路中电源通过第一变压器连接控制装置，控制装置连接测试装置，测试装置上放置有待测电容；控制电路中电源通过第二变压器连接整流器，整流器连接单片机，单片机连接控制装置并根据单片机设置形成脉冲信号，控制控制装置的通断。本发明主要利用了市电来产生一种可控相位的纹波来进行加速电容器样品的老化，继而检测其产品的失效时间，进而对该批产品的适用性进行评价。它对于不同型号的电解电容有较好的普遍适用性。
摘要（英）：

The invention relates to a controllable-phase ripple wave generator, and aims to solve the problem that the traditional capacitor test instrument adopts a complex test method and is of high cost. The device adopts a 220V municipal power source of which the output is connected with a test main circuit and a control circuit. In the test main circuit, the power source is connected with a control device through a first transformer, the control device is connected with a test device, and a to-be-tested capacitor is placed on the test device. In the control circuit, the power source is connected with a rectifier through a second transformer, the rectifier is connected with a single chip microcomputer, the single chip microcomputer is connected with the control device, and a pulse signal is formed based on the setting of the single chip microcomputer to control on-off of the control device. According to the invention, controllable-phase ripple wave is generated through the municipal power source to accelerate aging of capacitor samples, and then, the failure time of products is tested, and the applicability of the batch of products is evaluated. The controllable-phase ripple wave generator is of high general applicability to different types of electrolytic capacitors.
