    AC Input Filter Design 6 days left
    VERIFIED

    I’m looking forward to design a robust AC input filter for HiLink AC DC converter in which an AVR project is running. And I would like to add some prime features like inrush current protection, AC line transients / spike protection as well as inductive load back EMF protection which may sometimes reset the microcontroller. Please note we have only phase and neutral, so earth connection for the filter circuit. Please find the attached file of the proposed project.

    Hi I need to have a power supply system designed. Please see Mauch electronic as an example (shown below), but have distanced differences. Each voltage must consist of three individual PSUs with their outputs combined. Each individual PSU must deliver the design voltage @ 10A continuously and with short bursts @15A and current cut-off @ 20A PSU based on LM5116 reference design Output files in Altium format Requirements Input voltage 13.5V - 60.0V Supply from two input sources. Inputs must be isolated. Supply voltage from input 1 must NOT flow out input 2 Output voltages options – each output consist of one Molex P6 5.3v 2x Molex P6 + 1x Molex P4 Fan connector (three individual PSUs combined) 7.4v 2x Molex P6 (three individual PSUs combined) 12v 2x Molex P6 (three individual PSUs com...

    I need a Circuit Schematic Diagram for a Simple Sensor Switch. Operation modes: - The Circuit will be turned on Manually. - The Circuit will have 230V Input from Wall Plug. - The Circuit will give 230 V Output to a Water Pump. - The Circuit will have 1 or 2 open wires connected to it (Depending on your design), and the open end of these wires will be placed in the overhead water tank at a required level. - These wires will act as a sensor, when the tank is filled and water touches the open end of these wires the Circuit should cut off the output power to the WATER PUMP - The 230V Output to the WATER PUMP will not turn on until the MAIN SWITCH is turned OFF and back ON. Other Points to Consider: 1. Please do not use any MCUs just designs with simple ICs and resistors etc. 2. W...
