The power supplies in the first two modules of HEPHAISTOS cavity 3 are standard-ripple power supplies [rip], which are sufficient to ful- fill all requirements of normal microwave heating. Another type of low-ripple power supplies is used in the third module, which can be usedinapplicationsrequiringfasterandmoreaccurateoutputpower. (a)Standard-ripplepowersupply.
