High-frequency switching power supply needs of a digital controller SIR

Power equipment and other electronic devices, has been transferred to digital control of analog Latitude D505 Battery, Latitude D510 Battery control. , The high-power switching power supply has been greater use of digital control, ESP with the high-frequency switching power supply is usually more than 30 kilowatts ~ 100-kilowatt belonging to high-power switching power supply. 30MHZ ~ 300MHZ frequency of use of digital signal processor DSP to do the next bit machines, to achieve high-power inverter 20KHZ ~ 50KHZ real-time control is economically feasible. On the other hand, electrostatic precipitator power supply is generally not one, but up to 3 sets 8 sets or 10 sets or more electrostatic precipitator to control high-frequency switching power supply to achieve integration of cabinets and transformers are generally installed in the body next to the electrostatic precipitator , away from the control room. In order to achieve group control and remote control needs to host computer.

Electrostatic precipitator high-frequency switching power supply that is all-digital Latitude D520 Battery, Latitude D600 Battery control machine and under the upper position control, the relative analog control has the following advantages: (1) digital control of advanced control methods can be used (eg, using adaptive control), and intelligent control strategy, making ESP ESP a higher degree of automation; (2) control flexibility, system upgrade, it can set up online, modify the operating parameters, remote opening and closing power; (3) can be implemented with a hardware system are two different principles control, such as FM-based in order to achieve certain specific circumstances the same time, the tone width control; (4) digital transmission more reliable than analog transmission to further improve the reliability of the power, ease of standardization; (5) system, easy maintenance; (6) system-wide coherence, low cost, interrupt procedures and the use of branching processes eliminate a lot of hardware circuits, manufacturing convenience; (7) easy-to-the composition of parallel operating system, expansion of power capacity to meet the high-power electric precipitator demand; (8) can be both a Nikon MB-D40 Battery Grip, Nikon MB-D80 Battery Grip system of electrostatic precipitator equipment system control functions.
