The new control method that we adopt, change the inverse-excitation type control strategy of conventional fixed-frequency exactly, adopt the inverse-excitation type control strategy of changeable frequency, in the input voltage range of the whole non-constant width of power supply, the ON time that makes power MOSFET tube is much larger than the effective ON time of minimum.The control integrated circuit IC1 (seeing accompanying drawing 1, accompanying drawing 2) that we adopt is exactly the IC of variable frequency.
Adopted high pressure input voltage compensation technology simultaneously, allowed effective current to increase, improved controling environment under high input voltage along with the increase of input voltage.
At improving reliability, adopted energy attraction technology, surge voltage, surge current or the switching overvoltage interfering energy at scene are carried out clamp absorb.Adopt the input over-voltage protection technique, guaranteed the security of operation of module.
At energy-saving and cost-reducing, adopted quasi-resonance soft switch PWM technology, the frequency reducing rate technology when underloading, zero load, constant-current source starts Driving technique, PPFC (Passive Power Factor Correction) technology.
