UPS circuit with LM3524D
LM3524D is a kind of switch power supply controller which uses PWM operate mode. In the working mode, the pin 12 and pin 13 of LM3524D output pulse signals with the phase difference of 180°, whose voltages are amplified through VT1 and VT2 and then the electric currents are stimulated to be amplified by VT3 and VT4. As a result, both of the two processes drive the VT5 and VT6 to amplify the power of the pulse signals. The power amplifier VT5 and VT6 generates 12V square AV voltages on the one side of T2 transformer according to the alternating of the pulse signals outputting by VT1 and VT2.between turning on and turning off. After being stepped up, the square AV voltages are changed to 220 V AV voltages and are output through the other side of the transformer T2, which offer power supply for the load. The operating frequency of this circuit is decided by R2 and C1.VD2 and VD3 in this circuit is used to prevent the power amplifier from flowing through the current with a opposite direction. (View)

When one of the control buttons is pressed, the relay in this branch closes and is self-locked, and the LED shows the bed number. At the same time, the other group normally open contact closes to make the acoustic and optical alarm circuit work. VL12 and VL13 shines and BL sends a music alarm to remind the medical personnel to deal with it in time.

Eyesight Protection Reminder
When the indoor light is strong, the inside resistance value of light sensitive resistor is small. IC's 1 pin has a low level, and 2 pin has a high level. VD is connected and the controlled pulse oscillator doesn't work, so VL is not illuminated. When the indoor light is so weak as to reach a certain level, NOT gate circuit D1 will reverse and make VD disconnected. The controlled pulse amplifier begins to work and generates square form pulse signal. The signal will turn into narrow pulse signal after differentiating circuit and shaping circuit. Then after the signal is amplified by V, it will promote VL to work and twinkle with a certain frequency. (View)
