The high-frequency transformer in Figure 4 achieves an electrically isolated current feedback loop consisting of three pins of IS200VRTDH1DAB. When the output terminal is short circuited or the output is overloaded, the primary current of the transformer increases, causing the voltage of UC3844’s three pins to increase. When the voltage of the three pins is greater than 1V, the internal current amplifier narrows the conduction width to achieve the protection of MOSFET tubes and transformers.

IS200VRTDH1DAB power supply anti-interference design. External interference mainly comes from the input end of the power supply, so the circuit for releasing interference to the ground is mainly designed in the input circuit. There are two types of interference on the power line: common mode interference and differential mode interference. Common mode interference exists between any phase of the power supply and the ground, and differential mode interference exists between the phase and neutral lines of the power supply

IS200VRTDH1DAB and the use of EMI filters between phase lines can effectively suppress common mode interference and differential mode interference, significantly improving the anti-interference performance of switching power supplies. Therefore, the first line of defense is designed at the input end of the input filter. The input EMI filter circuit is shown in Figure 5.
