You didn't tell us what particular problem do you have with the WinSCP, so I can really only repeat what's in WinSCP documentation.

• Download WinSCP .NET assembly.
  The latest package as of now is WinSCP-5.17.9-Automation.zip;

• Extract the .zip archive along your script;

• Use a code like this (based on the official PowerShell upload example):

    # Load WinSCP .NET assembly
    Add-Type -Path "WinSCPnet.dll"
  
    # Setup session options
    $sessionOptions = New-Object WinSCP.SessionOptions -Property @{
        Protocol = [WinSCP.Protocol]::Sftp
        HostName = "example.com"
        UserName = "user"
        Password = "mypassword"
        SshHostKeyFingerprint = "ssh-rsa 2048 xxxxxxxxxxx...="
    }
  
    $session = New-Object WinSCP.Session
  
    try
    {
        # Connect
        $session.Open($sessionOptions)
  
        # Upload
        $session.PutFiles("C:\FileDump\export.txt", "/Outbox/").Check()
    }
    finally
    {
        # Disconnect, clean up
        $session.Dispose()
    }

You can have WinSCP generate the PowerShell script for the upload for you:

• Login to your server with WinSCP GUI;
• Navigate to the target directory in the remote file panel;
• Select the file for upload in the local file panel;
• Invoke the Upload command;
• On the Transfer options dialog, go to Transfer Settings > Generate Code;
• On the Generate transfer code dialog, select the .NET assembly code tab;
• Choose PowerShell language.

You will get a code like above with all session and transfer settings filled in.
