preface
After the launch of the Nano Gallium Nitride Super Charge, the well-known fast charging brand ANKER Anker has launched a gallium nitride charger with 100W output power. This charger provides two USB-C interfaces, supports 100W power blind plug, and provides a USB-A interface to support 22.5W fast charge output. This 100W charger supports charging three devices at the same time, with a small size and powerful performance.
The charging head network has obtained an ANKER Anker 736 Gallium Nitride super charge, which can be greatly reduced while supporting three output interfaces, and can be well supported for mobile phones and notebooks. Let's disassemble this charger to see how the internal materials and design are.

Anker 100W Gallium Nitride Super Charge Disassembly
After having a basic understanding of the appearance, size, performance, etc. of ANKER Anker 100W Gallium Nitride Super Energy Charge, the following is a detailed disassembly to see how the internal workmanship materials are.
Detach the charger along the input side housing seam and secure the housing with ultrasonic welding.
The front of the charger PCB is covered with a pure copper heatsink with tape insulation on the heatsink and foam gel cushioning between the heatsink and the housing.
The back of the PCB also uses pure copper heat sinks and black isolation plates to dissipate heat.
The input wires are welded and secured with thermal adhesive.
The heat sinks are soldered to the PCB for fixation.
The length of the PCBA module measured using a vernier caliper is approximately 51.1mm.
The width is approximately 62.6mm.
The thickness is approximately 26.5mm.
Soldering removes the heat sink on both sides of the circuit board, and the circuit board components are filled with glue in a large area to form a whole, fixing the components while strengthening the heat dissipation.
The back of the circuit board is fixed with thermal adhesive to fix an isolation sheet through the PCB isolation slot for primary secondary insulation.

In the upper right corner is the transformer, the thermistor is pasted above the transformer to detect the temperature rise, and the left side of the transformer is the high voltage filter capacitor. Below is the output secondary buck circuit that regulates the output voltage and output.

A glance at the back circuit board of the charger, the upper part is the PFC boost circuit, the left side is the flyback switching power supply, and the isolated slot position in the lower right corner is the secondary secondary buck circuit. Both the PFC and flyback switching power supplies use a nano-micro gallium nitride power chip. The two optocouplers are used for output voltage feedback and PFC control, respectively.
Through observation, it is found that this charger adopts the PFC+QR switching power supply architecture design, PFC performs power factor correction, QR flyback power supply performs fixed voltage output, and finally the secondary buck circuit identifies and adjusts the interface output voltage through protocol recognition. Let's start with the inputs to understand each device.
The right side of the charger PCBA module is the input terminal, which is equipped with an input fuse, EMI filter circuitry, and a rectifier bridge.
The AC input enters the charger through the input fuse, the delay fuse is from Bate Electronics, discharge number 932, specification 3.15A 250V.

The PFC power factor correction circuit compensates for the phase difference between the input current and the voltage by means of a boost, reduces the inrush current when charging the large-capacity electrolytic capacitor in the high-power charger, and avoids the impact of the inrush current on the power grid waveform. At the same time, PFC can also reduce the capacity of the primary electrolytic capacitor and reduce the volume of the charger by boosting.
The PFC boost controller adopts ON Semiconductor NCP1622BEC, which is an enhanced high efficiency boost PFC controller that operates in critical mode and boosts the output of the rectifier bridge to perform power factor correction for switching power supplies.
