A meromorphic differential on a Riemann surface is said to be {\it real-normalized} if all its periods are real. Real-normalized differentials surfaces of given genus with prescribed orders their poles form real orbifolds whose topology closely related that moduli spaces marked points. Our goal develop tools study this topology. We propose combinatorial model for the normalized single order $2$...

This paper presents an implementation of open loop and closed loop control of Quadratic boost converter using PID controller.  Quadratic boost converter consists of boost converter and fly back converter driven by a single switch. Quadratic boost converter QBC is designed especially for regulating the DC interface between various micro sources and dc-ac inverter to electricity grid. Quadratic b...

In this paper, a new transformerless buck-boost converter based on ZETA converter is introduced. The proposed converter has the ZETA converter advantages such as, buck-boost capability and input to output DC insulation. The suggested converter voltage gain is higher than the classic ZETA converter. In the presented converter, only one main switch is utilized. The proposed converter offers low v...

Analysis of generic single-pole, two-pole, and three-pole operational transconductance amplifiers (OTAs) is carried out based on settling time. The most important design metrics the open-loop frequency response, such as stability margins gain-bandwidth product (GBW) are related to time single-, two- three-stage OTAs in closed-loop configuration, enabling present a procedure for each OTA specifi...
