Embodiment Construction

[0022] The method of the present invention divides six processing links of phase control, pulse generation, pulse conditioning, control interface, storage space management and data exchange logic to realize the control pulse generation of power electronic equipment, figure 2 The principle block diagram of the implementation of the method of the present invention is given. Such as figure 2 As shown, when the synchronous signal input by the front-end signal processing part is adopted, the phase control part will perform synchronous processing on the synchronous signal, and generate phase scale data accordingly. When the synchronization signal is not used, the phase control part will use its internal frequency synthesis function to generate a phase pulse signal, and then count the phase pulses to obtain phase scale data. Then, the pulse generation part is based on the phase scale, and according to the state control data and pulse data in the storage space, logic operation is p...

Abstract

A method for generating the control pulses of electric power or electric equipment includes such steps as processing the synchronizing signals at front end or counting the amount of phase pulse signals to obtain phase scaling data, converting input control signal, storing it in storage space, reading out pulse data, comparing phase angle in it with said phase scaling data, logic conversion of pulse level to generate original pulse signal, and pulse shaping to obtain said control pulse. Its advantages include easy synchronization control, unified management of storage space, high data transmission efficiency and good speed match.

Description

Technical field: [0001] The invention relates to a method for generating a control pulse of a power electronic device. The signal generated by the method is mainly used in the power electronic device of a power system, and provides various square wave pulse control signals for the power electronic device, belonging to the field of power electronic control . Background technique: [0002] In the original power electronic equipment, the generation of control pulses is mostly implemented by analog methods, and these analog methods have many shortcomings. First of all, the number of devices used in the analog circuit is large, the circuit relationship is complicated, and it is difficult to debug and design. This design difficulty also makes the analog pulse generation circuit often have a single function, narrow application range, and poor flexibility. Secondly, potentiometers, dials and other devices are used in the analog pulse generation circuit to adjust the working condit...
