A synchronous rectifier alternator and a power allocation method thereof are provided. The synchronous rectifier alternator includes an alternator, a synchronous rectifier circuit and a controller. The alternator converts mechanical energy to alternating current (AC) electrical energy. The synchronous rectifier circuit converts the AC electrical energy to direct current (DC) electrical energy and provides the DC electrical energy to a load. The controller detects a voltage level of the DC electrical energy. When the controller detects that the voltage level is higher than or equal to a first threshold voltage value, the controller controls ONs and OFFs of first transistors and second transistors of the synchronous rectifier circuit, such that at least one of regulator diodes of the synchronous rectifier circuit, a stator of the alternator and the load consume power of the alternator.

A rectifier package module for a vehicle and a connection status detection method for a temperature sensor thereof are provided. The rectifier package module includes at least one temperature sensor and a control chip. The control chip has an end coupled to the temperature sensor through a bonding wire. The control chip generates a current and provides a reference voltage according to a mode selection signal. The current is provided to the temperature sensor through the bonding wire. The control chip compares a voltage on the end with the reference voltage to generate a comparison result. In a test mode, a comparison circuit generates the comparison result to indicate a connection status between the end and the temperature sensor.

A short circuit detection circuit and a short circuit detection method for a multi-phase rectifier are provided, which are used for detecting conditions of a spectrum of a FWR signal outputted from the multi-phase rectifier in the frequency domain. Next, determining whether the detected signal indicating the amplitude of the frequency of the AC signal is greater than or equal to the reference signal, so as to determine whether the multi-phase rectifier has a short circuit condition. Therefore, the short circuit detection circuit and the short circuit detection method do not have any requirements for configuring a short circuit detection element on each current path of the multi-phase rectifier, so that the power loss and the cost can be reduced effectively.
