Problems solved by technology

[0002] Conventional technology can only adjust the parameters of the DC end when adjusting and controlling the DC load. Under this limited control mode, many formed equipment cannot realize re-control and performance improvement, which makes many modern technologies impossible to implement. Regulating the AC source to control the DC load, enabling the AC control technology to be applied to the DC control, and realizing the new control concept and method of compound control of the DC load have not been reported yet.

Embodiment 1

[0029] Such as figure 2 As shown, this embodiment uses a thyristor as a driver, and its original-end control drive device specifically includes a thyristor TR as a driver and a purification and decoupling network Z1 connected in parallel with it. The phase-shift signal of the control signal is added to the control terminal of the thyristor TR, and the thyristor TR generates excitation to the isolation transformer B, which is coupled through the isolation transformer B, and then converted into DC by the rectifier bridge in the rectifier DC control part C. The first capacitor C1 filter and adjustable voltage regulator IC for DC control (it can also be an integrated circuit device with other functions, because the DC load is different, the control purpose is different, and the function of the integrated circuit used is different) and the second control adjustment potentiometer W2 is adjusted, and the second capacitor C2 completes re-filtering and then adds it to the DC load D (a...

Embodiment 2

[0031] The difference with embodiment 1 is: as diagram 2-1 As shown, the bipolar power device (which can be NPN, PNP or compound device) is used as the driver in the original end control drive device.

Embodiment 3

[0033] The difference with embodiment 1 is: as Figure 2-2 As shown, a field effect device (which may be various MOS, BIMOS, VMOS or other field effect devices) is used as a driver in the primary-end control driving device.

[0034] The mechanical actuator of the control is completed by the adjustment box connected to the first control adjustment potentiometer W1. The adjustment box of the present invention adopts a pedal structure, and the components of the original control part A are integrated inside, and the first control of the drive is completed by moving up and down. Adjust potentiometer W1 to rotate (or slide). As shown in Figure 3-1, there is a rubber foot 3 supporting the pedal body under the main body base 1 of the foot pedal. The arc-shaped rack 5 (the teeth are set on the inner side) meshes with the gear 6, and the gear 6 is connected to the adjustment end of the first control adjustment potentiometer W1. When the pedal 2 moves downward, the rack 5 is driven to d...

Abstract

The related control method for dc loading by ac regulation comprises: adding source-end control part on original rectification dc control part with parameters unchanged, regulating the additional control part to control dc loading for composite control. This invention improves large dc control method for more flexible.

Description

technical field [0001] The invention relates to a practical application technology for adjusting and controlling a DC load, in particular to a control method and a control device for AC regulation and control of a DC load. Background technique [0002] Conventional technology can only adjust the parameters of the DC end when adjusting and controlling the DC load. Under this limited control mode, many formed equipment cannot realize re-control and performance improvement, which makes many modern technologies impossible to implement. Regulating the AC source to control the DC load, enabling the AC control technology to be applied to the DC control, and realizing the new control concept and method of compound control of the DC load have not been reported yet. Contents of the invention [0003] The object of the present invention is to provide a control method and control device for AC regulation and control of DC load. The invention can realize the purpose of controlling the...
