/// Calculate transformer output power accounting for efficiency losses.
///
/// Uses a quadratic model where load losses scale with the square of output power.
///
/// # Arguments
/// * `input_power` - Real AC power input to the transformer in W.
/// * `transformer_rating` - Nominal output power of the transformer in VA.
/// * `no_load_loss` - Constant losses as fraction of rating (0-1).
/// * `load_loss` - Load-dependent losses as fraction of rating (0-1).
///
/// # Returns
/// Real AC power output in W.
