  One of the most challenging projects that we were not able to do without previous experience was this upcoming project. There are three main challenges for this circuit, first of all, a very high clearance of about 6 mm for the power part of the circuit, in the next step, the front space. It was specified by the customer and the isolation of 5 kV between the primary and the secondary, which complicated the design of the PCB and the transformer, as it is clear in the picture, basically two separate circuits are designed on one PCB, all parts of Power, controller, feedback and snubbers are separate and common only in the input part, the arrangement of the power part is such that the air flow of the fan hits all the parts, the selection of parts and values \u200b\u200bof the circuit elements is in a way that constantly and day and night with To work reliably, a UVLO part is also considered for the circuit, which turns the circuit into standby mode below 350 volts to prevent damage caused by current stress. The feedback of two main voltages is taken with IC 431 and applied to the control IC by optocoupler. The circuit works stably in DCM and CCM mode and its core is wrapped with the most optimal mode to have the highest isolation along with the lowest leakage inductance and leakage flux.
  In the gate driver circuit, many measures are taken to overcome the Miller capacitor, unwanted spikes and unpredictable conditions so that the circuit has the highest reliability.
  SMD parts were placed in the lower layer so that it can be easily assembled by the method of visual soldering.<\/p>\n","protected":false},"excerpt":{"rendered":"
