    """
    Converts a dictionary to a CSV file and saves it at a specified location.

    Args:
        data (dict): The data to be converted into CSV format.
        filename (str): The name of the output CSV file, without the '.csv' extension.
        position (str, optional): The file path where the CSV should be saved. Defaults to the directory of the caller script if not provided.

    Returns:
        None: The function does not return anything.
        
    Raises:
        FileNotFoundError: If the specified directory does not exist.
        PermissionError: If write permissions are lacking for the directory.
        TypeError: If `data` is not a dictionary.
        Exception: For other issues that may arise during the creation or saving of the CSV file.

    Example:
        >>> convert_to_csv({'id': [1, 2], 'value': [10, 20]}, 'output', '/path/to/save')
        Saves a CSV file named 'output.csv' at '/path/to/save'.
