The series–parallel resonant converter (also called line level control (LLC) resonant converter) is one of the most suitable topologies for dc–dc power supply. This study introduces the LLC resonant converter into the on-board battery chargers for the plug-in hybrid electric vehicle (PHEV) applications. Different from the previous literature which has focused on the wide operation range and hol...

This paper describes the operation, design, implementation and performance of RF coupled resonator filters. It starts by considering discrete parallel inductor/capacitor resonators and then moves on to discuss the implementation of this style of filter at higher frequencies using short circuit co-axial resonators in place of the inductors. Introduction Shunt mounted resonators, comprising a dis...

A microelectromechanical systems (MEMS) temperature sensor based on a cascade three-stage “bent-beam” structure is described in this paper. A suspended structure mechanically deforms in response to the change in ambient temperature, and then, a displacement is obtained; the structure is composed of three cascaded systems in order to enhance sensor sensitivity. The final conversion is made to an...

optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. the distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

This application note describes characteristics and design challenges of metal-oxide-metal (MOM) interdigitated capacitors and circuits containing MOMs. It also explains how the MOM capacitor design can be facilitated using F3D – a parasitic extraction tool based on a random walk method. I. MOM capacitor characteristics and design challenges 1. What is a MOM capacitor? Analog integrated circuit...

This paper presents an alternate quasi-resonant dc link (QRDCL) circuit for soft switched inverters which does not require paralleling of a charged capacitor with another charged capacitor or a voltage source. The circuit momentarily pulls down the DC link voltage to zero as commandled by the control circuit to facilitate zero voltage switching (ZVS) of inverter devices. Operation of this circu...
