Technical Field

[0001] The utility model relates to a multilayer conductor structure of a voltage-doubling rectifier circuit board, in particular to a commercial electric flame cooker. Background Art

[0002] Commercial electric flame stove is a stove used in commercial kitchens, commonly found in restaurants, banquets, restaurants, canteens, etc.

[0003] Commercial electric flame stoves are mainly composed of a high-voltage rectifier circuit and more than 100 electrodes that generate plasma flames. The high-voltage rectifier circuit is equipped with electronic components that are independently electrically connected to each electrode to give the electrodes a doubled high voltage output. In order to provide high voltage electricity to numerous electrodes, the existing technology arranges hundreds of groups of electronic components on a circuit board, and stacks or lays multiple circuit boards flat. However, the limited internal space of the commercial stove is a challenge, because the circuit layout needs to take into account not only the voltage-doubling rectifier circuit board itself, but also needs to leave space for other key components such as power modules, fire control components, transformers, resonant circuits, etc.
