To begin with, the power-supply integrated circuit (IC) is much more integrated ... a desired percentage of ripple current is less important in highly integrated, low-power step-down converters ...

a dual-channel IC delivering two very low noise, low ripple bias supplies from a single input. Each channel incorporates a monolithic step-up DC/DC converter post-regulated by an integrated ultra-low ...

Many novel approaches to reduce ripple have been tried by manufacturers, including placing a filter on the output of the single-phase power supply, but with limited success. Other low-ripple power ...

The results imply that low ripple power supplies hold a distinct advantage over the conventional single-phase power supply because of their ability to apply more power to the precipitator field.

The new IC increases continuous power to more than 1.6 kW and permits ... start-up control enable operation without an external bias supply, reducing system cost and complexity.
