supporting the grid voltage and proper operation of the grid-connected converters (GCCs) under a wide range of grid voltage conditions have become major requirements. An analytical study is very useful for evaluating the supporting capability of the available control strategies in GCCs. This paper analytically studies, then modifies the supporting capability of three existing strategies. The contribution of this paper is two-fold: first, analytical expressions of instantaneous active/reactive powers oscillation and maximum phase currents are formulated and used to conduct several comparisons among different strategies. Second, based on the obtained formulas for the maximum phase currents, maximum allowable support (MAS) control schemes are proposed under unbalanced voltage conditions. The MAS control schemes have two important objectives: obtaining maximum active or reactive power delivery and simultaneously respecting the maximum phase currents under the unbalanced condition. The proposed equations can further estimate the maximum depth of the faulted voltage where each strategy is still able to satisfy the voltage support requirements imposed by the grid codes. The proposed expressions can also help all techniques to provide their maximum voltage or frequency support under the pre-set maximum phase current limitations. Different selected simulation and experimental tests are carried out for comparing the strategies, and validating the effectiveness of the proposed MAS equations.

Calculator which provides facility to evaluate BODMAS expressions, has digital converters, financial calculator, and basic math formulae

Any mathematical expression can be expressed in infix, post-fix and pre-fix formats. This C application is a universal expression convertor implemented using stack data structure. This structure will take input of input expression and conversion option from the user and provide the output in the desired format. The goal of this application is to handle various mathematical operations by converting given expression.

command line calculator for windows (evaluator of math expressions and RPN converter)

Java implementation of an infix to postfix expression converter and evaluator using custom data structures.

This project implements an infix to postfix converter and evaluator for mathematical expressions. The program reads an infix expression from the user, converts it into postfix notation, evaluates the result, and prints both the result and the postfix expression.

A modular JavaScript calculator featuring an infix-to-postfix converter, stack-based expression evaluation, and dynamic button input handling for real-time computation.

The "infix-to-postfix-prefix-converter" repository on GitHub contains a C++ project that converts infix expressions to postfix or prefix notation and evaluates them using stacks. The project includes a main.cpp file that prompts the user for an infix expression and outputs the converted expression and its evaluated result.

An Expression Converter application that converts infix expressions to postfix format using the stack data structure. It visually demonstrates the step-by-step algorithm and provides an interactive interface for understanding how expression evaluation works in computer science.

Smart Expression Converter is a powerful web application that allows users to convert mathematical expressions between different notations—Infix, Prefix, and Postfix. It also evaluates expressions for quick results. Whether you're a student, programmer, or math enthusiast, this tool makes expression handling seamless and efficient.

C++ implementation of an Infix to Postfix Converter and Postfix Expression Evaluator using the Stack data structure. Supports operators (+, -, *, /, %, ^), functions (sin, cos, tan, sqrt, log), variables, implicit multiplication, and error handling. Demonstrates core DSA concepts like stacks, parsing, precedence, and file handling.

python to latex converter using Sympy's latex printing for most mathematical functions but avoids the term reording (and perhaps a few evaluations) incurred working with fully "sympified" sympy expressions (even those created with the evaluate=False keyword). Based on Geoff Reedy's program at https://stackoverflow.com/a/3874621/1391250

This library evaluates a string which represents a mathematical expression. It also offers other methods which are relevant to this operation. Methods like tokenizer which splits the string into individual mathematical tokens (such as operators, operands, parenthesis, etc.) and infix to postfix converter, etc.
