Description

Microcomputer power conditioner

This creation is about a microcomputer power conditioner, especially a microcomputer power conditioner with power saving and voltage regulation effects and protection when it encounters abnormal conditions.

Press, the traditional voltage regulator mainly uses the automatic control transformer to stabilize the voltage, increase or decrease the voltage, and stabilize the voltage of the supply equipment. However, the use of a transformer to force a step-down to achieve power saving for certain devices has also been widely used, and such devices that use a transformer to force a buck to save power still have many disadvantages, in which the cost of the transformer device is large because of the large amount of current. It is expensive and bulky. Therefore, in order to improve its economic effect, it is generally only applied to a larger overall power system. However, after use, the voltage drop is too large, and it is easy for some devices to malfunction due to undervoltage, and the voltage is lowered. If it is too small, it will not achieve the desired power saving effect. In addition, the transformer with step-down power saving is generally used, and the voltage drop cannot be flexibly adjusted. Therefore, the voltage drop is too large or too small, and the voltage drop is too large, which may cause the equipment to operate abnormally. If the drop is too small, the power saving effect is not obvious. Moreover, there is no power saving system at present. When the output voltage is stabilized, the output voltage output to each load can be adjusted according to the operation of each load, thereby causing the operator to spend unnecessary power costs. .

At present, the general power-saving device usually uses capacitors and resistors as the main components to improve the power factor, so as to save power. Because the load and service life of the capacitor are quite limited, when the capacitor is damaged or short-circuited, the savings cannot be achieved. The purpose of power, but the power consumption situation is the same, or the user is short-circuited and internalized by the power saver. The power consumption situation cannot be immediately detected and replaced or repaired, which often causes user troubles and even damages to its transformer device or electrical equipment.
