400w integrated llc/pfc+l semi-bridged circuit condenser bp3599

Bp3599 is a high-performance llc semi-interruptible circuit controller for integrated high-voltage start-up and power supply. It's by creating a 50% complementarities-driven waveform
Drive llc semi-bridge condensers。
Bp3599 adjusts the output voltage or current by changing the working frequency. Llc semi-bridge converter has a very wide sensory workspace and can easily achieve zero voltage
Zvs, more efficient and less efficient。
The bp3599 integrated resistance switch mechanism effectively avoids an acceptable switch in a start-up, output short circuit or output overload state。
Bp3599 also provides automatic dead zone functionality to avoid access to hard switches, reduce switch losses and increase efficiency。
A soft start is installed in bp3599, which can effectively reduce current and voltage over startup charge

Main performances
High pressure start and power supply
 50% symmetrical space ratio variability drive, precise pressure control oscillation device
Zero, it's a constant flow function
It's soft
Perceptive mode protection
Zero, automatic dead zone
 programmable input without pressure protection
Lightweight intermittent working mode
 rich protective function
Two levels of excess protection (ocp)
 output overload protection (olp)
 output short circuit protection (scp)
 output overpressure protection (ovp)
 vcc under pressure protection (vcc uvlo)
Vcc overpressure protection (vcc ovp)
 temperature protection (otp)
 enter pressure protection (brown out)

Rationale
1. Llc semi-bridge conjunctive transformer pouncer
The llc semi-bridge condensator consists of a level 3 circuit, as shown below, i. E. The square wave generator, the resonance network and the current network。
 the square wave generator produces the square wave voltage vsq through 50% of the space-to-space alternation switches q1 and q2. Usually, introduce in q1 and q2 driver switches
A smaller dead zone time。
 the resonance network consists of the resonance of the electric capacity, the resonance of the electric sense and the magnetic sense。
 the current network produces direct current voltage, and the current of communication is fixed using the current diode tube and the capacitor. The current network can be designed as a central pump structure or whole
Wave-wide stream bridge。
