读今年本刊二期陈先生“再谈松下TC—25V40RQ型彩电STR—S6708电源电路分析”一文后,我认为在理论分析上仍有欠妥之处。我怀着与陈先生相同的心情,对该电源电路提出个人看法。如有不妥之处,望同行们指正。一、STR—S6708 ⑦脚稳压控制端的电压不是越高主电压输出越高,而是⑦脚电压越高,输出电压越低(反之亦然)。只要我们仔细分析一下该电源电路的稳压过
Read this year’s second issue of Mr. Chen “talk about Panasonic TC-25V40RQ color TV STR-S6708 power circuit analysis,” a text, I think there is still a defect in the theoretical analysis. I feel the same with Mr. Chen, on the power circuit put forward personal views. If there are any problems, hope colleagues correct me. One, STR-S6708 ⑦ feet voltage regulator control voltage is not higher the higher the main voltage output, but ⑦ the higher the voltage, the lower the output voltage (and vice versa). As long as we carefully analyze the regulator over the power circuit
