[0021] 测量电路主要包括U3-A和U3-B,采用LM324芯片,其内部有四个运算放大器,此处使用其中的两个(U3-A和U3-B)运放作为稳压器输入电压U1和输出电压U0的测量电路。 [0021] The measuring circuit includes a U3-A and U3-B, using the LM324 chip, its interior has four operational amplifiers, as used herein, two of which (U3-A and U3-B) as the regulator input op amp U1 and U0 voltage measuring circuit output voltage.

首先阐述U2的逻辑缓冲作用。 First elaborated the logic buffer U2. 如果没有U2的逻辑缓冲作用,因为单片机Ul在刚一上 If there is no logical buffer U2, because in just a microcontroller Ul on

电时其端口H)可能输出为全“ I ” (PD=FFH=I 111111IB ),这个全“ I ”信号(8个高电平)就会直接加在U4 (ULN2803)的输入端,会导致U4内部YO〜Y7的输出为低,从而使八个继电器都吸合动作,进而它们的常开触点JO〜J7全部同时闭合,这会使自耦调压器的八个绕组短路,会烧毁整个调压器的。 Its electrical port H) may be output for the whole "I" (PD = FFH = I 111111IB), the whole "I" signal (8 high) will be directly applied to U4 (ULN2803) input terminal, cause U4 internal YO~Y7 output is low, so that the eight relays are energized action, and then they all normally open contacts JO~J7 closed simultaneously, which makes auto regulator eight winding short, it will burn entire regulator. 所以应该是任何时刻,要么JO〜J7全部断开,要么仅有一个为闭合状态,其余为断开状态。 So it should be at any time, either JO~J7 all turned off, or just a closed state, the rest is disconnected. 采用U2以后,就可以解决上电瞬间继电器全吸合的问题。 After use U2, we can solve the power instantly relay the full pull of the issue. 单片机上电瞬间,U2的复位电路(RlO和C2)为U2的清零端)提供一个低有效上电复位信号,使U2的输出为全“O”(Q7〜Qq=00H=00000000B),从而使U4内部的8个OC门驱动器全部截止断开,进而使8个继电器全部断电,其8个常开接点J7〜JO不闭合,输出电压U0=O。 MCU power moment, U2 reset circuit (RlO and C2) to clear terminal U2) provides a low effective power-on reset signal, the output U2 for the whole "O" (Q7~Qq = 00H = 00000000B), thereby make U4 inside eight OC gate drive are all turned off disconnected, thereby enabling the eight relays all off, the 8 normally open contacts J7~JO not closed, output voltage U0 = O.

[0023] 同时,Ul的复位电路(R9和Cl)为Ul的复位端(NRST)提供一个高有效上电复位信号使单片机复位,程序从初始化部分开始运行,首先立即向ro 口写入全“o”(ro=ooH),并经过PC7产生一个由低到高的电平变化,使U2的CLK端获得一个上升沿触发信号,从而将ro口数据(此时为8个全“O”)锁存进入到U2 (74LS273)的输出端(Q7〜Qq=OOH=OOOOOOOOB)。 [0023] Meanwhile, Ul reset circuit (R9, and Cl) as Ul reset terminal (NRST) provides a highly efficient power-on reset signal and reset the device, the program starts to run from the initialization section, first written immediately to the ro mouth full. " o "(ro = ooH), and after PC7 produce a low to a high level changes, so that the CLK terminal U2 obtain an edge-triggered signal to the ro port data (in this case eight full" O ") latched into U2 (74LS273) output terminal (Q7~Qq = OOH = OOOOOOOOB).

[0024] 此后,单片机进入正常的工作循环。 [0024] Thereafter, the device enters the normal operating cycle. 对输入电压UI和输出电压UO进行检测和判断。 UI input voltage and output voltage UO detection and judgment. 并根据表2,通过单片机的ro 口输出数据,该驱动数据经U2和U4使得相应的继电器吸合,从而保持输出电压的稳定。 And according to Table 2, through the microcontroller ro port output data, the driving data by U2 and U4 so that the corresponding relay, so as to maintain a stable output voltage.

这样,当输入电压在173〜275V之间波动变化时,输出电压都能稳定在额定电压220V上。 Thus, when the input voltage fluctuation between 173~275V, the output voltage can be stabilized at the rated voltage of 220V.

[0026] 本发明不仅局限于上述具体实施方式,本领域一般技术人员根据本发明公开的内容,可以采用其它多种具体实施方式实施本发明,因此,凡是采用本发明的设计结构和思路,做一些简单的变化或更改的设计,都落入本发明保护的范围。 [0026] The present invention is not limited to the specific embodiments, those of ordinary skill in the disclosure of the present invention may be used to implement other more embodiments of the present invention, therefore, the present invention is designed all structures and ideas and do Some simple changes or design changes are within the scope of the claimed invention.
