The connection mode of the silicon carbide rod components can be connected in series or in parallel, preferably in parallel. When used in series, the number of branches in series should not be more than 3. The determination of the resistance is based on its own needs, depending on the situation.
The power supply equipment of silicon carbide rods is a good choice for equipment with a large voltage regulation range and stable and continuous voltage regulation, such as magnetic voltage regulators, thyristor AC and DC voltage regulators, etc. If you choose a stepped voltage regulating transformer, you should also choose a transformer with a small voltage difference and a large number of voltage regulating gears.
