Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0022] The present invention constructs a multi-parallel and multi-cascade complex power electronic conversion system, as shown in the attached figure 1 As shown, the system includes a remote control host, multiple drive controllers, and multiple power devices corresponding to the drive controllers. The remote control host is respectively connected to the local drive controllers 1, 2, ... N through the downlink signal lines 1, 2, ... N, and the signals transmitted by them respectively include drive information 1, communication information 1, ... drive information N, communication information N. Encode the drive information 1, 2, ... N and communication information 1, 2, ... N on the host computer through the high and low levels and the conduction time of the high and low levels, and then decode the local drive controller to convert the The ab...

The invention relates to a driving and communication signal processing method based on a same physical line. According to the method, driving signal and communication signal lines are transferred and resolved through a physical line by a parallel multistage complex power electronic transformation system; the system comprises a remote control host, a plurality of driving controllers and a plurality of power devices corresponding to the driving controllers; the remote control host is respectively connected with local driving controllers 1, 2, ...N through downloading signal lines 1, 2, ...N, and transferred signals respectively include driving information 1, communication information 1, ...driving information N and communication information N; the driving information 1, 2, ...N and the communication information 1, 2, ...N are coded on the host through high-low level and conducting time of the high-low level and then are decoded on the local driving controllers, so as to separate the driving information and the communication information. The driving and communication signal processing method has the following advantages that (1) the system communication lines are greatly reduced, so that the cost is reduced; (2) an implementation way is simple and effective.
Description
technical field [0001] The invention relates to a signal processing method, in particular to a method for simultaneously transmitting and analyzing a driving signal and a communication signal on a physical signal line. Background technique [0002] With the rapid development of the economy, my country has gradually increased its investment in high-power, high-voltage power transmission, flexible direct current transmission, high-speed rail, etc., making power electronics technology develop in the direction of high-power, high-voltage parallel and cascaded applications. breakthrough. [0003] For multi-parallel and multi-cascade complex power electronic conversion systems, it includes a remote control host and multiple local drive control units. The host needs to send the drive signal to the local drive control unit through the transmission line, and then strengthen the weak signal through the drive control unit and apply it to the power electronic device to complete the high...
