New Description: [New Technology Field] This creation involves the age-type electric service relay, especially the digital power control device that can touch and stabilize the current. "" [Prior Art] As known, in order to make the electrical appliance operate normally, it is necessary to provide a stable and appropriate power supply during the operation of the electrical appliance, and a power supply with a suitable current/voltage value, Protecting electrical appliances, improving the service life of electrical appliances, and energy-saving and energy-saving effects; based on the above purposes, a power controller can be disposed between the power supply and the power input end of the electrical appliance to regulate the power supply output and the appropriate power supply electrical appliance operation; As shown in the fourth figure, the conventional power supply control device of the pulse width modulation (pulsewidthmGdu on n PWM) controller architecture mainly includes a voltage adjustment unit that can control the output power of a power switch to achieve regulation. The purpose of the power output, and the adjusting unit has a thief fixed voltage value of the temple, and the current is in the range of 〇·5~xiao; the voltage regulating unit further includes a comparator. Connected to the aforementioned reference voltage source and the output end of the detection loop, the comparator is used to detect the reference % provided by the reference voltage source. The difference between the feed and the Vft is generated, and according to this, a false signal (E«ge) is generated, which is used to indicate which signal value is relatively large. V is connected to the -PWM control network. Therefore, the comparator can be increased or decreased by the ratio of the reference value _ system and (4) ', m W 颂 electric dust Vfb', according to this Drive this? Observe the lightning output of the power switch... The paste is used to control the power level, so as to regulate the output of the appropriate power. 5 M366240 Supply electrical operation. However, the conventional power supply control device often causes the accuracy of the power output to be difficult to control due to factors such as the error of the sense resistor impedance on the detection loop, the error of the reference voltage, and the line loss. Generally, the highest accuracy is only about 2 %~25% or so, and when it is configured for different output voltages, it must be changed to the relevant components to meet the requirements, which has caused many problems in application; in addition, in order to improve the accuracy of power output, Some power control devices have been adapted to digital voltage regulation units. For example, US Patent No. 6,995,995 "Digital loop for regulating dc/dc C() nver^" — segm_d switching) The return number of the detection loop must be converted into an analog/digital converter for signal conversion processing, the analog signal is converted into a digital signal, and then calculated by the operation loop. Stealing the value, relying on the number of health signals to control the group of switches composed of most MOS-FETs, according to which the output power is regulated; The price of components such as the W-like digital converter and the MOS tree_array is very high, which is a problem that has been overcome by such a power control device. • [New Content] • In view of the fact that the main purpose of this creation is to provide a digital power control device, the difference between the wheel and the wheel can be changed by the setting in the memory, without changing the power control device as in the prior art. External circuits and parts can increase the convenience of the application. This creation sub-purpose wire supply-type touch type Wei (four) device, its _ digital control = PWM controller can accurately output the required duty cycle 1 Qing & postal reach the set output voltage 'easy to reach 〇 5% or less of the output error, so the purpose of regulating the output voltage. 6 M366240 Age-old Γ — —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— —— ——

When the number of sampling times meets our preset requirements, the addition and division circuit of the modulation control period control unit 7 calculates a pWM power value that meets the demand. ^ Output module 8 controls the power switching unit to have a suitable duty.

The object, s can be known as 'this creation by the digital PWM output module 8 can finely control the output of the analog output of the second analog, the output of the analog 2 pulse line (four) _, easily achieved, therefore Can be a large __ accuracy, the upper pole Ar Dan _ range; in addition, the creation of the output voltage value of the modulation 1 Ί via the technical adjustment (four) Cap Storage Jing control number value can be 12 M366240 to meet the output demand The voltage value does not need to be changed to other circuit units, so it does not increase the design cost and the difficulty of the production technology. In addition, the creation can use the operation record and product identification data stored in the simon memory to Convenient for future management, debugging and follow-up. The present invention is not limited to the above-described forms, and it is apparent that with reference to the above description, there can be more improvements and changes in technical equivalence. Therefore, any modification or alteration of the creation made in the same creative spirit should still be included in the scope of protection of this creation. φ [Simplified description of the drawings] The first figure is a functional block diagram of the preferred embodiment of the present invention; the second figure is a circuit diagram of the feedback voltage value encoding unit of the present embodiment; The input and output waveform diagrams of the device; and the fourth diagram are functional block diagrams of the conventional digital power control device.
