The difference between the full bridge and the half bridge of the commercial induction cooker

First, the same and different operating principles of commercial induction cooker:

The same point: after a series of circuit processing skills, ordinary AC (220V, 380V) is converted into high-frequency DC current, after the intense eddy current occurs in the power line disk, and the electromagnetic field is induced by the corresponding special pot, directly promoting the corresponding special The inside of the pot data is extremely fast and turbulent, and then the corresponding special pot itself is heated and hot, which is used to process cooking food!

difference:

1. In the acceptance conversion processing skills of AC:

Full bridge: Select dual-drive technology, use the dual IGBT inverter module to receive the upper and lower Xuan wave currents of the converted AC, and the high-frequency current waveform is intact, clear and stable;

Half-bridge: Select single-drive technology, use a single IGBT inverter module to separate the upper Xuan wave from the converted AC, contact the corresponding additional circuit equipment to absorb the Xuan wave current for discharge compensation, and the high-frequency current waveform is relatively intact;

2. In the load sensing of the corresponding special pot:

Full bridge: Due to the high power of current conversion skill and equipment, it can load higher inductive load, and the electric heating power is correspondingly higher.

Half bridge: due to the low power of the current conversion skill and equipment, it can load a lower inductive load, and the electric heat transfer power is correspondingly lower.

Second, the use of the manifestations of similarities and differences: by the respective circuit principle difference resolution:

The same point: can be reached so that the corresponding special pot itself is hot and hot, and the intention to process the cooking food is reached.

difference:

1. In the power segment:

Full bridge: the power distribution of the corresponding gears is clear and clear, and the response is agile.

Half bridge: the power distribution of the corresponding gear is more ambiguous, and the response is relatively reasonable.

2, on the heat surface:

Full bridge: due to the high load load, the heating surface is larger and more uniform, the layering can be reduced step by step, and the flame simulation effect is remarkable.

Half bridge: Because the load can be low, the heating surface is small, the uniformity is less, the layering is clear, and the flame simulation effect is less. China Kitchen Equipment Network

Garden Support

Garden support is the ideal support for any climbing plants, vine plants, flowers and leaves. The plant finds support by growing up through the stake, to keep the plant up. We have several kinds of support, twisted spiral tomato support, plant support, garden trellis.
