    振荡控制电路的第三电感l3的波形以及跟随第三电感l3的波形变化而变化的第二开关管q2、第三开关管q3的波形，其中，第二开关管q2和第三开关管q3的波形为正导通，波形为0截止。由于电感l1的端和第三电感l3的端互为异名端，第二电感l2的端和第三电感l3的端互为同名端，所以第三电感l3的波形与第二电感l2、电感l1同频率，与第二电感l2同相位，与电感l1反相位。当第三电感l3处于正弦波的正半周时，第三开关管q3导通，第二开关管q2截止；当第三电感l3处于正弦波的负半周时，第三开关q3截止，第二开关管q2导通。通过第三电感l3同频率地控制第二开关管q2和第三开关q3的导通和截止，第三电感l3有效的反馈了由电容c1、电感l1和第二电感l2组成的振荡回路，形成了稳定的闭环控制，使工作时的振荡波形稳定。第二开关管q2和第三开关管q3在第三电感l3控制下交替导通与截止，第二开关管q2和第三开关管q3的状态变化，会同频率引起振荡回路的改变。当第三开关管q3导通且第二开关管q2截止时，形成以“第二电感l2和电容c1串联，再与电感l1并联”的振荡回路，如图5所示；当第三开关管q3截止且第二开关管q2导通时，形成以“电感l1和电容c1串联，再与第二电感l2并联”的振荡回路。静安区供应AD16系列蜂鸣器代理品牌AD16-16系列蜂鸣器寿命长，耗能低，体积小，重量轻，可靠性好，造型美观和制造精巧，声音清脆警醒。

    故在电路中起着自动调节、安全保护、转换电路等作用。在大多数的情况下，继电器就是一个电磁铁，这个电磁铁的衔铁可以闭合或断开一个或数个接触点。当电磁铁的绕组中有电流通过时，衔铁被电磁铁吸引，因而就改变了触点的状态。继电器一般可以分为电磁式继电器、热敏干簧继电器、固态继电器等。本实验板上配置的继电器如图9-15。图9-15继电器实物图继电器也是属于感性器件，所以不能用单片机的I/O口直接来控制，且要在三极管等控制器件上加反相保护电路。一般实验中都是单片机通过一个PNP型三极管，把三极管作为电子开关来驱动继电器，继电器的开和关完全由三极管的基极电平进行控制。当三极管基极为高电平，PNP型三极管截止，这时继电器不工作；反之为低电平的话，PNP型三极管导通。
