DESC:The Regler is basically an AC voltage regulation and control device that can maintain constant AC voltage at its output irrespective of any incremental voltage at its input under such condition any input AC voltage surge or high voltage spikes are also blocked by the unit and by the process of maintaining a fixed value constant voltage the electrical energy delivery to any load can be controlled and optimized to a value where no wastage of energy occurs and also the connected loads do not directly suffer any variations of ac voltage so electrical equipments lives gets elongated.
As shown in the diagram the in coming mains AC voltage is first rectified using the brigde rectifier B1 and provided to resistors R1 and R2 and then to a 9Volts zener diode Z1 and filter capacitor C1 this 9V dc volage is used to power the comparator IC U1. Resistors R3 and R4, R5 provides the mains AC ripple voltage to the non inverting terminal of caparator IC U1, R6 and R7 provides low voltage reference to the inverting terminal of U1, the output from U1 is a zerocrossing voltage that is integrated using R8 and C2. The zerocrossing integrated waveform is provided to the second comparator and its DC reference is provided through the optocouplers U3’s output transistor whose collector is connected to the capacitor C7 and resistor R20 to provide ripple free DC as reference to the second comparator the output of this compartor is given to a opto thyrister driver IC U2 and the DC voltage to the IC is provided through resistors R9,R10 and the combination of zener and capacitor Z2 and C3 and resistor R11. The output of this opto driver is given to two back to back SCR’s SCR1 and SCR2 with current limiting resistors R12,R13,R14 and SCR gate protection diodes D1 and D2. R15 and C4 acts as snubber for the SCR’s. The output AC voltage from these SCR’s is passed through the line filter inductor L1 and provided to filter capacitor C9 across neutral this phase and neutral output goes to the load to which electrical power needs to be controlled. Again the output from the SCR’s is rectified using bridge B2 and provided to resistors R23 and R24 in series with zener Z3 to generate a 9Volts DC ripple voltage this voltsge is used to power LED2 through R25 for power indication and seprate resistors R21 and R22 provides feed back voltage from the output of the SCR’s this voltage is filtered using C8 and given to potontiometer POT1 and variable zener VZ. This zener inturn is connected to the optocoupler IC U3’s IRED through R19. When ever the output voltage of the SCR’s goes above the value set by the reference pot POT1 the zener ZV starts conducting through U3 and enables transistor of the optocoupler this in turn increases the DC reference voltage of the second comparator of U1 and adjusts the firing angle of the IC U2 and reduces the total RMS voltage and once the ZV set value is reached ZV stops conduction and the voltage gets locked to the set value, in this when ever the input voltage increases the output voltage from the SCR’s remains regulated and maintains a constant value under any input voltage variable conditions. The U3 IC’s opto IRED is also connected in parallel with an NPN transistor Q1 biased through R17 and R18 with capacitors C5 and C6 in parallel, when the switch SW is ON the DC ripple 9Volts starts charging capacitors C5 and C6 through R17 and based on the time constant set value when the capacitor’s voltage goes above 0.6 voltas the transistor starts conducting and disables the opto IRED and as the capacitors fully charges the IRED is totally disabled and in this condition the out voltage of the SCR’s have no control over the mains AC voltage and the mains voltage is directly avalible at the output of the SCR’s this condition is also known as by pass mode because the mains is directly avalible from the SCR’s, this condition is indicated by the LED1 connected through R16. Again when the switch SW is OFF the capacitors slowely discharge due to its ESR (Equivalent Series Resistance) and the unit goes intto automatic requlation mode this condition is known as Eco mode, hence the whole system works as a closed loop control AC voltage regulator and can be switched to by pass mode or regulation mode using switch SW and the change over from one mode to another mode is decided by the charging and discharging of capacitors C5 and C6. ,CLAIMS:1) A Device to reduce electrical power consumption and reduce electricity consumption in any premises like industrial or domestic acting as a relatively high power AC regulator that can regulate the power consumption of any electrical equipment connected to its output
