An apparatus for supplying power to multiple APD receivers is disclosed, including: a bias high-voltage generating circuit, connected with parallel APD receivers through a bus, and adapted to generate a bias voltage and distribute the bias voltage to tributary APD receivers through the bus. The apparatus also includes an adjusting and detecting circuit, set on each APD tributary, connected between a bias high-voltage generating circuit and an APD, and adapted to adjust the voltage value distributed to each APD according to the requirement of each APD. The APD receiver power supply apparatus under the present invention provides power supply to multiple APD receivers, thus avoiding the complicated high-voltage generating circuit required in the prior art, reducing the cost, and enabling the apparatus to occupy less space.
