MultiPhase-RD is an advanced electrical power supply and current control technology, with the application fields in DC/DC & AC/DC (Off-Line) SMPS , providing solutions for isolating and controlling ac/dc power supplies at greater than 10 kW.

The benefits of this technology can be quickly realized in the area of reducing the size and increasing efficiency for power systems. The basic concept of the MultiPhase-RD technology is to utilize a blend of multiple small current sources and current control to deliver a much higher maximum output current than a conventional setup.

The MultiPhase-RD current control technology achieves efficiency levels up to 98% while significantly reducing the need for large heatsinks. This benefit is achieved from the high efficiency of the drivers used in the system.

The MultiPhase-RD current control technology is based on a module with four parasitic capacitors which, when used to construct a power supply, enable the unit to operate in a single or dual mode. In the single mode, the module operates in a constant current mode, providing a wide dynamic range and voltage range. In the dual mode operation, two modules are connected together in a serial arrangement, allowing up to 4x the output current compared to the single mode configuration.

In the implementation of the MultiPhase-RD technology, programmable digital current controllers are used to regulate the output current and voltage of the power supply. The controllers offer very precise current and voltage control, as well as a wide range of user options, including a variety of control modes, overvoltage protection and input voltage sensing.

Current control can be implemented using digital signal processors (DSPs), microcontrollers (MCUs), or even field programmable gate arrays (FPGAs). The choice of technology depends on the application requirement and the requirements of the power supply. Digital signal processors offer the greatest flexibility, with the ability to program multiple functions or multiple current controllers. The Digital signal processor also enables the current control algorithms to be easily changed or customized.

In order to achieve the desired current control characteristics, multiple components are used in the power supply system. The power supply system includes primary components such as transformer, filter inductors, switch, gate drivers, and protection devices, as well as secondary components such as a current/voltage regulator, an input filter, overvoltage detection circuit, and protection circuits.

The technology can be applied to a variety of applications, including high power DC/DC and AC/DC switching power supplies, as well as some power supplies designed for the automotive industry. In automotive applications, the current control technology can be used to achieve high performance, while providing improved efficiency and reduced design complexity.

In conclusion, the MultiPhase-RD current control technology offers performance and efficiency benefits in many DC/DC and AC/DC (Off-Line) SMPS applications. The technology is ideal for applications that require high performance and efficiency, while providing improved design complexity and reduced size. With its wide range of features and benefits, MultiPhase-RD technology is suitable for a wide range of applications.
