Description

technical field

[0001] The invention belongs to the technical field of controllers, and in particular relates to a control system based on bidirectional energy conversion. Background technique

[0002] Today's converter control system is developing from traditional two-level to multi-level control. Multi-level control can achieve control requirements more accurately, but it also uses a large number of switching devices for control, and each switching device requires one PWM to complete the control, so the control chip needs to generate multiple complementary PWM waveforms to achieve control. In recent years, with the vigorous development of programmable logic devices, FPGA processing and computing capabilities have been greatly improved, and have been favored by the power electronics industry. FPGA can reorganize internal logic circuits and triggers through Verilog hardware programming language, and can realize large-scale information processing through state triggers. Whe...
