A Comprehensive Procedure for the Design of Cascaded Swkched - Capacitor F ilters
نویسندگان
چکیده
A complete set of design equations is given for first-order and biquadratic transfer functions in the z-domain. These equations are derived directly from the firstand second-order transfer functions in tbe s-domain. Consequently no new approximation for a prewarped set of cutoff frequencies is required. A step-by-step design procedure for SC filters follows. The sampling-conditions for input and output signals and for cascading are also discussed.

A Novel Controller Based on Single-Phase Instantaneous p-q Power Theory for a Cascaded PWM Transformer-less STATCOM for Voltage Regulation
In this paper, dynamic performance of a transformerless cascaded PWM static synchronous shunt compensator (STATCOM) based on a novel control scheme is investigated for bus voltage regulation in a 6.6kV distribution system. The transformerless STATCOM consists of a thirteen-level cascaded H-bridge inverter, in which each voltage source H-bridge inverter should be equipped with a floating and iso...

A two stage sub-µW Inverter-based switched-capacitor amplifier-filter is presented which is capable of amplifying both spikes and local field potentials (LFP) signals. Here we employ a switched capacitor technique for frequency tuning and reducing of 1/f noise of two stages. The reduction of power consumption is very necessary for neural recording devices however, in switched capacitor (SC) cir...

A multilevel inverter is capable of generating high-quality stepwise pseudo-sinusoidalvoltage with low THD , applicable to high-power and high-voltage systems. These types of topologiesmay require a large number of switches and power supplies. This leads to much cost, large size, andcomplicated control algorithms. Thus, newer topologies are being proposed to decrease the numberof power electron...
