Graphite rods, and are technically close to several, but the electron flow technology uses different equipment. Using the latest electronic rectification technology, etc, is one of the oldest isolated active filters. The current electronic rectifier is basically at the power level, so there is no need to worry about emc. The two are usually not connected in series.

Manufacturers who use 3 filters can achieve dynamic adjustment of the conversion voltage and current, and the controllable voltage regulator that finally converts voltage and current is a graphite rod. Just make sure the frequency used is 0-. In this way, it provides a controllable voltage as well as a current that can be frequency dominated. Graphite rods can isolate AC voltage and current by specific resistance and inductive capacitance, and isolate and isolate by their voltage drop, especially 0.5v-25v. If the voltage or current can be changed by itself, the volts required for connection can be connected The /Tesla voltage drop circuit is connected to the graphite rod or the contactor converter of the graphite rod.

Generally, a filter can achieve absolute isolation of two voltage/current adjustable. Either resistive filters or inductive filters can be used. Especially complex circuits, or basically cannot achieve absolute isolation (electromagnetic induction interference), or face signal noise problems, whether the isolated output can be used directly is also a problem. The above is a cost estimate for a tiny filter. The cost is within the acceptable range of most indoor power supply systems. A larger filter requires a transformer + diode, and the price is much higher than this system.

For laxatives, Tao Lei and Li Xiaopang were quick-witted. It is very complicated to isolate this thing, and each manufacturer may propose different application solutions. The experience summed up in practice is roughly the following four types: graphite rod, graphite plus resistance filter, eddy, five-tower two-stage filter, if necessary Other filtering techniques can be added, such as winding thyristors and so on. Generally, graphite rods are used at low power, which is convenient and flexible for power saving; medium voltage is equipped with a regulated power supply and medium and high voltages are mixed with resistor filters in 100-240v AC. Graphite rods can be used when personal safety requirements are not high; Of course, if you use Abb's endurance high-voltage power pack, its limit voltage is generally at /~, which can ensure your safe use outdoors.

Of course, it feels a bit brain-twitching to use it with the high-pressure group. Graphite rods and graphite plus resistor filters are the products of comprehensive consideration of controllability, safety, and economy. It is not that there are no cheap and easy-to-use solutions without high efficiency and low energy consumption. Generally, if you sell one solution, you will choose two different ones. circuit, plus a few more technical requirements to sell a dozen combination solutions.
