Embodiment Construction

[0018] refer to Figure 4 , The power supply control system of the present invention is composed of three major parts: a group of POL or PB power supply, a digital power supply controller (hereinafter referred to as the main controller) and an isolated power stage converter (Isolated Power Block).

[0019] First of all, the system includes a group of traditional POL or PB power supplies to supply power to the load; the isolated power stage converter is responsible for the conversion of the input voltage to the bus voltage. There is no internal controller, and PWM signals need to be provided externally. The isolated power stage converter can communicate serially with the main controller. The serial bus includes clock lines and signal lines, and the serial communication method can be I2C or SPI.

[0020] The main controller based on DSP or MCU is not only used to control and monitor the POL or PB in the system, but also responsible for controlling and monitoring the isolated po...

Abstract

The invention discloses a power supply control system. The power supply control system comprises a group of POL (Point of Load) or PB (Power Block) power supplies, a digital power controller and one or more isolation power level converters connected in parallel and is characterized in that the group of POL or PB power supplies are used for supplying power to a load; the isolation power level converter takes charge of converting input voltage to bus voltage and is communicated with the digital power controller; the controller is arranged in the isolation power level converter; the digital power controller is used for monitoring the POL or PB in the system and monitoring according to the type of the isolation power level converter. The power supply control system can reduce the cost, saves PCB spaces of the isolation power level converter, improves the power density of the isolation power level converter, improves the light load efficiency and optimizes the efficiency of the overall system.

Description

technical field [0001] The present invention relates to the field of intermediate bus power system (Intermediate Bus Architecture, IBA), in particular to a power control system. It proposes a new system architecture and method for implementing input voltage to bus voltage conversion in intermediate bus powered systems. Background technique [0002] With the development of electronic technology, the complexity of electronic systems is getting higher and higher, and usually the types of power supplies required in an electronic system are gradually increasing. In order to solve these problems, the power supply system of the intermediate bus structure is widely used at present. Such as figure 1 As shown, this is a traditional intermediate bus structure power system. First, an isolated DC / DC converter is used to convert the input voltage to an intermediate bus voltage, and then multiple non-isolated point load power supplies (POL-Point of Load) are used to convert the The inte...
