Embodiment Construction

[0028] In order to make it easier for those skilled in the art to understand and implement the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Overall structural block diagram of the present invention is as figure 1 As shown, by adding an MCU to the existing power loop to organize the relevant data of the power loop, using the communication interface to exchange with the control loop, and using a separate signal line instead of the state data, it can solve the two problems caused by the large number of state signal lines. Compared with the connection method of a single signal line, it can provide rich and accurate information data, and can perform some simple auxiliary control functions through the MCU.

[0030] The MCU and the control loop can be connected through the communication bus, using SCI (Serial Communication Interface), SPI (Serial Peripheral Interfac...

Description

technical field [0001] The present invention relates to a power control device, in particular to a microcontroller-based intelligent power circuit and power board Background technique [0002] In the current inverter application systems such as servo drives and frequency converters, most of them adopt a structure in which the power loop and the control loop are separated. [0003] The control loop needs to collect relevant status information in the power loop and make corresponding controls. In most current application systems, the status information and control information are transmitted between the power loop and the control loop through separate signal lines. With the improvement of the intelligent level of the system, more and more status information and control information are required, and the number of signal lines connected between the power loop and the control loop will increase accordingly. The signal lines connecting the power loop and the control loop need to...
