This paper presents techniques to assist the power supply designer in accurately modeling and designing the control loop of a switchmode DC/DC power supply. The three major components of the power supply control loop (i.e., the power stage, the pulse width modulator and the error amplifier) are presented with power stage modeling being the focus of this presentation. The power stage is modeled ...

developers choosing standard high-voltage power supplies, the specialized nature of highvoltage power calls for a power supply selection process that reflects the unique characteristics of the high-voltage power supply and its operation. High-voltage power supplies drive a broad range of applications across diverse segments, including semiconductor, scientific, medical, industrial, and more. De...

The increasingly larger scale of integration in electronic systems has demanded a corresponding increase in the density of the power supplies of these systems. To some extent, this demand has been met by resorting to higher switching frequency power converters (-1 MHz). One of the major problems with high frequency switching converters is the generation of radio frequency signals which may inte...

Introduction The widespread use of battery operated portable devices such as cell phones and laptops has created the need for DC to DC conversion power supplies such as switched mode power supplies. According to an Electric Power Research Institute (EPRI) study [1], the amount of electricity that flowed through switched mode power supplies in 2004 was “6% of the national electric bill”. The pro...

Switch-mode power supplies represent a particular class of variable structure systems (VSS). Thus, they can take advantage of non-linear control techniques developed for this class of systems. In this paper the so called sliding mode control is reviewed and its application to switchmode power supplies is discussed. Sliding mode control extends the properties of hysteresis control to multi-varia...

The use of cardiovascular implantable electronic devices (CIEDs) has proved to be the most successful device-based therapy reduce morbidity and mortality disease over decades. evolution power supplies always promotes development CIEDs from historical perspectives. However, with increased demands energy, modern still face huge challenges in terms longevity, size, reliability supplies. Recent adv...
