This model is proposed and validated in previous scientific literature for CFLs in 230V 50Hz systems. <span style="font-family: OptimaLTStd; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;">Nevertheless, the derivation of this model is not straightforward to follow and its performance in 120V 60Hz systems is a matter of <span style="font-family: OptimaLTStd; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;">research work. In this paper, the analytical derivation of this CFL model is presented in detail and its performance is discussed when <span style="font-family: OptimaLTStd; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;">predicting the current of a CFL designed to operate in a 120V 60Hz electrical system. The derived model is separately implemented <span style="font-family: OptimaLTStd; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;">in both MATLAB<span style="font-family: OptimaLTStd; font-size: 5pt; color: #231f20; font-style: normal; font-variant: normal;">® <span style="font-family: OptimaLTStd; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;">and ATP-EMTP<span style="font-family: OptimaLTStd; font-size: 5pt; color: #231f20; font-style: normal; font-variant: normal;">® <span style="font-family: OptimaLTStd; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;">software using two different sets of parameters previously proposed for 230V 50Hz CFLs. These <span style="font-family: OptimaLTStd; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;">simulation results are compared against laboratory measurements using a programmable AC voltage source. The measurements <span style="font-family: OptimaLTStd; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;">and simulations considered seven CFLs 110/127V 60Hz with different power ratings supplied by a sinusoidal (not distorted) voltage <span style="font-family: OptimaLTStd; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;">source. The simulations under these conditions do not properly predict the current measurements and therefore the set of parameters <span style="font-family: OptimaLTStd; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;">and/or the model itself need to be adjusted for 120V 60Hz power grids.</span></span></span></span></span></span></span></span></span><br style="font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px;" /></span></span></span></span></span></span></p>
