Transfer Switch Controller Active Inductive Load Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transfer switches and controllers face challenges in efficiently managing high inductive loads, such as air conditioners, which can overload generators, particularly in scenarios where generator power output is near maximum capacity, leading to inefficient use of available power and potential shedding of other loads.
Innovation Solution
A transfer switch controller that monitors generator power output and determines the maximum peak startup power required for loads, allowing them to start only when sufficient power is available, storing this data for future reference to optimize generator utilization and prevent overloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If generator power output is near maximum capacity, then generator utilization is high, but inductive loads cannot start without overloading the generator
Solution Approach 1:
The controller performs preliminary assessment of available generator capacity before allowing inductive load startup. It calculates the difference between maximum power output and current power output, and compares this against the peak startup power requirement stored in memory, thereby preventing overload before it occurs
Solution Approach 2:
The controller continuously monitors generator power output and uses this feedback to dynamically determine whether inductive loads can startup. The system stores peak startup power data from previous operations and uses this information to make real-time decisions about load permitting, optimizing generator utilization while preventing overload
2Productivity
If traditional transfer switches are used without active load control, then device complexity is low, but load shedding occurs reducing productivity
Solution Approach 1:
The transfer switch controller automatically monitors generator capacity, stores peak startup power data, and makes intelligent decisions about load permitting without external intervention. The system serves itself by continuously assessing available capacity and autonomously determining which inductive loads can startup, thereby preventing unnecessary load shedding
Solution Approach 2:
The patent replaces traditional mechanical interlock mechanisms with an electronic controller that uses microprocessors, memory storage, and computational algorithms to manage load control. This substitution enables sophisticated decision-making about inductive load startup based on real-time generator capacity assessment

AI summary
A transfer switch controller is for a transfer switch, which cooperates with a plurality of loads including an air conditioner. The transfer switch controller includes a first input structured to input a thermostat start request signal for the air conditioner, a second input structured to determine power consumed by the loads, an output structured to output a start signal to the air conditioner, and a circuit. The circuit cooperates with the first input, the second input and the output. The circuit causes the start signal to be output by the output responsive to the thermostat start request signal of the first input if the determined power consumed by the loads is less than the difference between a predetermined maximum power output of a generator and a previous maximum peak start up power consumed by the air conditioner.
