Power Supply Design Notes: How to Measure Ripple

WebA coupled inductor filter is used for steady state ripple cancellation. This filter allows the MHD lamp to avoid the acoustic resonance phenomenon. To improve the efficiency of the ballast, a synchronous buck converter is used for the DC/DC converter stage and a frequency control method is proposed. WebThe inductor current decrease during the off state is given by: IL (–) V O Vd IL RL –VI L TOFF The quantity ∆IL(–) is also the inductor ripple current. In steady-state conditions, the current increase, ∆IL(+), during the on time and the current decrease, ∆IL(–), during the off time are equal. Otherwise the inductor WebThe buck converters can be modeled by the following bilinear models: (2) L j d i L j dt = v i n j · u j-v o (3) C j d v o dt = i L j-v o R. where L j and C j are the converters’ inductor and capacitor, i Lj is the inductor current, v in j and v o are the input and output voltages, R is the load resistance, u j is the control input, and j = 1, 2. land rover chelmsford lookers
