Smart bypass diode bridge rectifiers
Example implementations relate to smart bypass diode bridge rectifiers. For example, a device can include a power over Ethernet input. In some examples, the device can include a plurality of smart bypass diodes connected to the power over Ethernet input to form a bridge rectifier. In some examples, the device can also include a powered device connected to the bridge rectifier.
1. A network device, comprising:
a first power over Ethernet input connected to a first plurality of smart bypass diodes that form a first bridge rectifier, wherein the first power over Ethernet input is arranged to be connected to a first power source equipment device;
a second power over Ethernet input connected to a second plurality of smart bypass diodes that form a second bridge rectifier that is connected to the first bridge rectifier, wherein the second power over Ethernet input is arranged to be connected to a second power source equipment device; and
a powered device connected to the first bridge rectifier and the second bridge rectifier, wherein the second plurality of smart bypass diodes in the second bridge rectifier is arranged to prevent a reverse bias from providing power to the second power source equipment device.
2. The network device of claim 1 , wherein providing power to the second power source equipment device from the second bridge rectifier deactivates the second power source equipment device.
3. The network device of claim 1 , wherein the first bridge rectifier and the second bridge rectifier accept a coupling from type A power source equipment devices and type B power source equipment devices.
4. An access point, comprising:
a first power over Ethernet input connected to at least four smart bypass diodes that form a first bridge rectifier, wherein the first power over Ethernet input is connected to a first power source equipment device that provides power to the first bridge rectifier;

a powered device connected to the first bridge rectifier and the second bridge rectifier, wherein the second plurality of smart bypass diodes in the second bridge rectifier is arranged to prevent a reverse bias from providing power to the second power source equipment device; and
a load connected to the powered device and the first bridge rectifier.
5. The access point of claim 4 , wherein the first power over Ethernet input is connected between a first smart bypass diode and a second smart bypass diode of the at least four smart bypass diodes of the first bridge rectifier.
6. The access point of claim 5 , wherein the second power over Ethernet input is connected between a third smart bypass diode and a fourth smart bypass diode of the at least four smart bypass diodes of the second bridge rectifier.
