Third, LLC topology circuit
1. LLC oscillation circuit structure
Figure 5 is an LLC resonant circuit of a single resonant capacitor structure. The LLC oscillator circuit consists of an oscillating capacitor Cr, a primary side LP, a leakage magnetic inductance Lr, a magnetizing inductance Lm, and two MOSFET tubes and two half-bridge rectifier diodes on the secondary side. Among them, there are two oscillation networks composed of three components: Cr, Lr and Lr. One is an oscillation network composed of Cr and Lr. The oscillation frequency of this oscillation network is independent of the load. The other is Cr and Lm. An oscillating network composed of Lr. The oscillation frequency of this network is related to the weight of the load. Generally, the heavier the load, the higher the resonant frequency of the circuit.

The JUK universal Screw Terminal Block series has the typical features which are decisive for practical applications:
l The universal foot allows the terminal blocks to be easily snapped onto the NS35 or NS32 DIN Rail with G shape.
l Closed screw guide holes ensure screwdriver operation perfect.
l For terminal block with different wire cross-sectional areas, complete accessories are available, such as end plates, partition plates, etc.
l Potential distribution achieved by fixed bridges in the terminal center or insertion bridges in the clamping space.
l Same shape and pitch Grounding Terminal Blocks as the JUK universal series.
l Adopt ZB marker strip system,achieve unified identification.
