DC HIGH VOLTAGE WITH ATX STANTBY TRANSFORMER SCHEMATIC CIRCUIT DIAGRAM

In a prior project, I constructed a 12V to 220V DC-DC converter using an ATX power supply transformer (EI28). This time around, I employed the same circuit and achieved a voltage output of 910V DC.

Important Note: Please exercise extreme caution when operating this circuit as it generates high voltage. It is imperative to take all necessary safety precautions. Keep in mind that the 220V output is not suitable for powering AC devices such as TVs or monitors.

This segment operates somewhat autonomously from the main circuit. In essence, the control system’s power supply operates independently. When the computer’s power button is pressed, it activates the power circuit, while the computer’s operating system is turned off. This enables the +5 volts to be supplied from the USB port for operation.

Now we use this transformer in most atx power supply circuits, we used the transformer reversed 🙂 Since the input voltage is DC 12V, the primary part of the output (220V 10W lamp connected) second part is used as input.

Similar to other power supply types, an SMPS (Switched-Mode Power Supply) serves the purpose of conveying power from a source, typically an AC outlet, to a DC device. What distinguishes an SMPS is its capacity to finely control the output voltage. It possesses the ability to raise or lower the output voltage as necessary, ensuring a stable output even when the load fluctuates.

An SMPS is an electronic power supply system that employs a switching regulator to efficiently transmit electrical power. It functions as a PSU (Power Supply Unit) and is commonly found in computers, where it adjusts the voltage to the appropriate range required for the computer’s operation.
