| 摘要 |
The invention relates to a flexible digital controller for power converters, such as inverters, which includes: a first processor which manages the human-machine interface, communications, etc.; and a second processor controlling converter management modules which connect with the power modules. Each processor is provided with a switching controller, memories, buses, timers, etc. The information exchange between processors takes place via RAM memory and FIFO. The converter management modules are divided into: a block for managing driver signals, which includes three-phase PWM and dead-band control and signal decoders for fault detection; and a block for acquiring signals of voltage transducers, which includes channels for measuring AC output current and DC current and channels for measuring the AC and DC voltage. |
