For controler:

public function actionUpload() {
    $base_path = Yii::getAlias('@app');
    $web_path = Yii::getAlias('@web');
    $model = new UploadForm();

    if (Yii::$app->request->isPost) {
        $model->file = UploadedFile::getInstanceByName('file');

        if ($model->validate()) {
            $model->file->saveAs($base_path . '/web/uploads/' . $model->file->baseName . '.' . $model->file->extension);
        }
    }

    // Get file link
    $res = [
        'link' => $web_path . '/uploads/' . $model->file->baseName . '.' . $model->file->extension,
    ];

    // Response data
    Yii::$app->response->format = Yii::$app->response->format = Response::FORMAT_JSON;
    return $res;
}

For model:

namespace app\models;
use yii\base\Model;
use yii\web\UploadedFile;

/**
 * UploadForm is the model behind the upload form.
 */
class UploadForm extends Model
{
    /**
     * @var UploadedFile|Null file attribute
     */
    public $file;

    /**
     * @return array the validation rules.
     */
    public function rules()
    {
        return [
            [['file'], 'file']
        ];
    }
}
