BACKGROUND

Inductors can be termed coils, chokes, or reactors. Inductors can be a passive two-terminal electrical component that can store electrical energy in a magnetic field when electric current flows through the inductor. In some examples, an inductor can oppose a change in current that is flowing through the inductor. In some examples an inductor can have a particular inductance, which can be a ratio of voltage to a rate of change in the current.

DETAILED DESCRIPTION

An inductor can be a device or circuit that includes inductance. As used herein, inductance includes an electromotive force that is generated by a change in electrical current. The inductance can be utilized to oppose changes in electrical current. Inductors described herein can be utilized to couple a first circuit assembly to a second circuit assembly by including a first lead positioned on a first side of the inductor and a second lead positioned on a second side of the inductor. In this way, the first circuit assembly can be positioned above the second circuit assembly to provide additional cooling for the first circuit assembly. For example, an inductor can include a first lead positioned on a first side of the inductor to couple the inductor to a first circuit that includes a power supply for a second circuit, and a second lead positioned on a second side of the inductor to couple the inductor to the second circuit to provide electrical power from the power supply to electrical components coupled to the second circuit.

In some examples, the inductors described herein can be utilized to provide power filtration between a first circuit assembly and a second circuit assembly. As used herein, power filtration includes receiving electrical power at an input and providing the electrical power within a particular voltage range at an output. That is, the inductors described herein can receive electrical power at an input lead that can include pulse width controlled rectangular wave voltage and filter the received electrical power to be within the voltage range that is utilized by electrical loads.

In some examples, a power supply can be coupled to the first circuit assembly to provide electrical power to a power stage coupled to the first circuit assembly. In some examples, the power stage can be coupled between the power supply and the first lead of an inductor coupled to the first circuit assembly. For example, a connector can be positioned on the first circuit assembly to couple the power supply to the first circuit assembly. In this example, the connector can be coupled to the power stage to provide electrical power to the power stage. In this example, a first lead of an inductor can be coupled to receive the electrical power from the power stage on the first circuit assembly and a second lead of the inductor can be coupled to the second circuit assembly to provide the electrical power from the power stage to the second circuit assembly. In some examples, the electrical power provided to the second circuit assembly can be filtered by the inductor and utilized to power a number of electrical components coupled to the first circuit assembly.

The inductors described herein can be utilized to couple a first circuit assembly that includes a number of electrical power connectors, electrical power connection lines, and/or pulse width modulation (PWM) controllers to a second circuit assembly. The second circuit assembly can include a number of components to be powered by the electrical power provided by the first circuit assembly through an inductor coupled between the first circuit assembly and the second circuit assembly.

In some examples, utilizing the first circuit assembly to couple the power connectors, electrical power connection lines, and/or the PWM controllers can reduce the quantity of electrical power connection lines on the second circuit assembly. In this way, the “quiet side” of the second circuit assembly can be increased, which can lower a level of noise on the second circuit assembly. In addition, utilizing the first circuit assembly to couple the power connectors, electrical power connection lines, and/or the PWM controllers can provide the same impedance path as having the power connectors, electrical power connection lines, and/or the PWM controllers on the second circuit assembly.

In this way, the first circuit assembly410can remove noise from the second circuit assembly412. In some examples, the noise created by electrical connections or electrical conductive lines can interfere with communication lines. In this way, the first circuit assembly410can remove noise from the second circuit assembly412, which can increase a “quiet area” of the second circuit assembly412. As used herein, the “quiet area” can be an area where communication lines can be positioned with a noise level below a threshold that can affect communication being transferred through the communication lines. Thus, the system420can be utilized to increase the “quiet area” of the second circuit assembly412to allow additional components to be positioned on the second circuit assembly412.

In this example, the system load516can receive the converted electrical power through the inductor502, which can prevent or oppose a change in the current of the provided electrical power.

In some examples, the power stage522can utilize a switching mechanism to convert electrical power received from a power source (e.g., power supply514, etc.). For example, the power stage522can include a first switch544and a second switch546coupled to a driver540. In this example, the driver540can be coupled to a pulse width modulation (PWM) controller524.
