Webcommon practice is to determine the worst case RHPZ frequency and set the loop unity gain frequency below one-thirdof the RHPZ frequency. In the Flyback topology, the equation for the RHPZ is: (5) The worst case RHPZ frequency is at the maximum load where IOUT is the highest and at minimum input voltage where the duty cycle D is the highest. WebAbstract: Flyback DC-DC converters are often used as power supply for many electronic systems because of circuit simplicity. However, the conventional flyback converter has a drawback of instability occurrence due to a right-half- plane zero.
