style="color:#000000;">参考开源广场的之前的两个项目，设计了这款桌面风扇。</span></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"><span style="color:#000000;">桌面风扇采用了触摸无极调速以及DC输入、QC诱骗输入两种电源方案，成本极低，造假约为15RMB左右。</span></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"> </p> <h3 class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt"

pap-spacing-after-3pt" style="line-height:1.8;"><span style="color:#000000;">项目首次公开，未参加过其余的任何活动及答辩。</span></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto

style="line-height:1.8;">3、开源协议</h3> <hr class="horizontal-splitline normal-bold-2"> <p>采用MIT开源协议，设计部分主要参考了https://oshwhub.com/wzw666/yan-wu-jing-hua-qi的灵感思路，电源部分参考了https://oshwhub.com/LiiGuang/du-li-yuan-jianqc2-0-gu-ding12v-you-pian-qi。</p> <p style="line-height:1.8;"> </p> <h3 class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">4、硬件部分</h3> <hr class="horizontal-splitline normal-bold-2"> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"><span style="color:#000000;">硬件电路部分十分简单，主要由三部分构成：</span></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"><strong><span style="color:#000000;">（1）QC诱骗12V输入</span></strong></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"><span style="color:#000000;">这部分采用分立元器件的设计，由小米充电宝提供12V/1.5A的电源输入。1N4148提供0.6V的基准电压，3400以及U11、19、20、12和R4构成延时的D-上的0.6V输入控制。</span></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"><span style="color:#e03e2d;"><strong>注意</strong>：这五个阻容的具体值应该认真调试，具体涉及到0.6V的延迟时间以及MOS的阈值电压，建议在仿真软件中测试过后再购买阻值元件。</span></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"><strong>（2）DC12V输入</strong></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">这部分没什么要说的，值得一提的是两个电源的输入部分为了安全，都增设了保险丝以及TVS二极管，为了控制成本，这两部分也可以不加。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"><span style="color:#000000;"><span style="font-size:14px;">（3）PWM触摸无极调速</span></span></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"><span style="color:#000000;"><span style="font-size:14px;">项目采用的是四线PWM调速风扇，由于这个转速反馈电压是霍尔传感器采集，在0-12v横跳，故不考虑反馈部分。根据SGL8022W触摸无极PWM芯片，提供两路PWM互补输出脉冲（因为有的风扇可能是根据高电平的持续时间控制转速的），请根据需求短接R5、R6.</span></span></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"><span style="color:#000000;"><span style="font-size:14px;">SGL8022W的设置方式如下：<img src="//image.lceda.cn/pullimage/XVwdlpVObZHCRvQDHyYP8WnvsocxCzQWt6Lh2fGL.jpeg" alt="XVwdlpVObZHCRvQDHyYP8WnvsocxCzQWt6Lh2fGL.jpeg"></span></span></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"><span style="color:#000000;"><span style="font-size:14px;">采用方式3——连续有记忆功能的PWM调速。</span></span></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;"><span style="color:#e03e2d;"><span style="font-size:14px;">注意：风扇对PWM频率有限制，低频PWM触摸芯片可能无法使用。</span></span></p> <p class="paragraph text-align-type-left pap-line-1.3
