| Abstract: | In order to implement digital control in high power medium frequency 400Hz/115V inverters,the delay induced by the processes of sampling,computing and PWM during digital control and its impact on the system performances are analyzed based on two-H-Bridge cascaded topology.The control parameters are designed in the continuous domain design by introduced the equivalent time delay when P+resonant controller are adopted.The discrete simulation on a single-phase 100kVA medium frequency inverter model was present... |
