Constant Power Medium Frequency Strike Control Board
Product Name: Constant Power Medium Frequency Strike Control Board
R & D cycle: 6 weeks
Product Description:

Circuit including three-phase synchronization, digital trigger, the last stage drive circuits, etc. Trigger part adopts digital trigger-off.it has high reliability, high precision, debugging easier etc. Characteristics. Digital flip-flop is characterized YongJi (the clock pulse)
Several measures to realize phase shifting, this digital trigger clock pulse oscillator is a kind of voltage controlled oscillator, the output pulse frequency phase shifting control voltage by the Uk's control, the Uk decrease oscillation frequency is increased, and the counter plan of numerical is fixed (256), counter pulse frequency and high, means JiYiDing pulse count the time needed for short, i.e., delay time is short, alpha Angle, and vice alpha small Angle. Counter start counting time also by synchronizing signal control, the alpha = 0 start counting. Now suppose in the Uk, according to a certain value when the vco the control voltage and frequency relations between determine output oscillation frequency for 25KHZ, then in count to 256 pulse the time needed for (1/25,000) x 256 = 10.2 (ms) is equivalent to about 180 ° electricity Angle, this flip-flop counting reset pulse in synchronous voltage (line voltage; 30 ° place, this is equivalent to 3-phases full controlled rectifier circuit beta = 30 ° position, from reset pulse on, delay 10.2 ms produce output triggering pulse, i.e. close to three-phase bridge rectifier circuit a certain phase thyristor alpha = 150 ° position, if need to get the exact alpha = 150 ° triggering pulse, can appreciably adjust potentiometer W4. Obviously there are three sets of the same trigger circuit, and vco and Uk to control the voltage for public use, so in a cycle produces 6 ° triggering pulse 60 phase difference. Digital trigger advantage is working stability, especially with HTL and CMOS digital integrated circuits, can have very strong anti-interference ability.
