| Popis: | The current mode control, which is one of the control methods for dc-dc converters, can realize high stability and quick response compared with the voltage mode control. The peak current mode control is generally implemented because it performs such properties and is easy to implement. In the digital control switching power supply, it is important control method because it eliminates a bad influence of delay time included in the controller. The purpose of this paper is to discuss the immune design of peak current mode control with current - frequency conversion to the inherent delay, which is the cause of an incorrect action, in the Field Programmable Gate Array (FPGA). As a result, the timing adjustment of processed signals in FPGA can realize a proper operation without major change of the configuration of proposed method. |
