Problems solved by technology

[0005] However, the use of the thyristor power regulator will bring some new problems to the circuit: First, after voltage regulation by the thyristor, waveform distortion will occur in the circuit, which will reduce the power factor and cause the system to overheat, thereby reducing the service life of the equipment; secondly, The thyristor power regulator will cause serious harmonic pollution to the system, degrade the power quality and cause electromagnetic compatibility problems
In order to reduce harmonics, it is usually necessary to insert a filter at the back end of the thyristor power regulator (as shown in Figure 1), which will not only increase the cost of the equipment, but also reduce the stability of the entire system by using too many additional equipment and security

Embodiment approach

[0070] It is not difficult to verify that the use of inductive components as the starting impedance can also effectively reduce the starting current of the system. Compared with the first embodiment shown in FIG. 2 , the advantage of using the inductance element as the start-up impedance is that it consumes very little energy, so it can effectively reduce the power loss of the system and improve the energy utilization rate.

[0071] Please refer to Fig. 4, the application system of the starting device provided by the third embodiment of the present invention, as another improvement scheme for the first embodiment shown in Fig. 2, the difference is that the capacitance C element instead of the resistor R element as the start-up impedance.

[0072] Except for the different start-up impedance, the structure, start-up process and related parameters of the start-up device provided by this embodiment are similar to those of the first embodiment shown in FIG. 2 , and will not be repe...

Abstract

The invention provides a starting device, a starting method and a power supply system for improving the starting current in a circuit. The starting device is connected in series with a heating element and consists of a starting impedor and a starting switch which are connected in parallel. When the heating element is started, the starting switch is turned off so as to turn on the starting impedor to divide the voltage and limit the current of the path; and after the heating element is fully started, the starting switch is turned off to make the two ends of the starting impedor have a short circuit, so that the heating element can work at a rated working current. The method for improving the starting current in the circuit comprises the following steps: connecting the starting device in series with the heating element; starting the heating element and turning off the starting switch at the same time; and after the heating element is fully started, turning off the starting switch. The power supply system comprises the starting device and / or the starting method. The starting device, the starting method and the power supply system have the advantages of effectively reducing the starting current, along with simple structure, no harmonic pollution and the like.

Description

technical field [0001] The invention relates to the technical field of circuit control, in particular to a starting device, method and power supply system for improving starting current in a circuit. Background technique [0002] With the advancement of technology, large-scale and automated production methods have become an inevitable trend in today's industrial development. At the same time, the scale and operating power of production equipment are also increasing. Therefore, maintaining the safety and stability of the power supply system and production equipment has become a major problem to be solved urgently by those skilled in the art. [0003] For example, in the production equipment of solar cells, the power supply system of the infrared radiation heating lamp tube (hereinafter referred to as the infrared lamp tube for short) used for preheating the silicon wafer has the problem of excessive starting current. The reason is that most of the filament materials of infra...
