Another feature of the USB Type-C plug is that it has rounded edges, and this provides the benefit of a self-aligning characteristic as the plug is inserted. With previous connector designs the user is required to visually inspect the connector to determine the correct orientation or go through a trial and error process inserting the connector creating a mild yet all too familiar inconvenience.

This enables the plug to be inserted faster and with more ease than previous USB connector designs. The USB Type-C (also referred to as USB-C) connector design is symmetrical so that it can be plugged in either way, meaning there is no right side up or upside down. This feature can be particularly useful for charging batteries.

USB Programmable Power Supply: is a supplemental specification to USB Power Delivery describing how the load and power supply communicate for incremental power delivery levels.

USB Power Delivery increases the power capability of USB to 100 W and is particularly useful when providing power to multiple devices.

USB Power Delivery: is a specification which allows the load and power supply to negotiate for multiple standard power delivery levels.

USB Type-C: is a standardized USB connector benefits include the compact, sleek, and reversible design.

In this post we'll discuss the relationship between USB Type-C, USB Power Delivery, and USB Programmable Power Supply, as well as how they relate to power supplies. These enhancements make USB an excellent option for delivering power, whereas in the past USB was primarily a provider of data and signal with limited power capabilities. The latest developments applicable to power supply designs include the USB Type-C connector, USB Power Delivery specification, and USB Programmable Power Supply specification. During this time there have been numerous changes to the specifications to improve the performance of systems employing these standards. The architecture of USB (Universal Serial Bus) has been in use as a standard for connectors and their associated signals and power delivery since 1996.
