Shared Simmer Power Supply for HVPT Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems with high-voltage-pulse-triggered (HVPT) devices, such as arc and flash lamps, are large and inefficient due to the need for separate simmer power supplies for each device, making them costly and space-consuming.
Innovation Solution
A simmer control circuit that selectively couples a single simmer power supply to multiple HVPT devices using a power supply circuit, trigger circuits, simmer switch circuits, a simmer drive circuit, and a device select circuit, allowing for the simultaneous operation of multiple devices with a single power source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate simmer power supply is used for each HVPT device, then each device receives reliable power, but the system size and complexity increase
Solution Approach 1:
The patent combines multiple separate simmer power supplies into a single shared power supply that serves multiple HVPT devices. The control circuit selectively couples the shared power supply to different devices, eliminating the need for individual power supplies for each device while maintaining reliable power delivery.
Solution Approach 2:
The shared simmer power supply is designed to universally serve multiple HVPT devices through a control circuit that can selectively couple the power supply to any connected device. This multi-functional approach allows one power supply to replace multiple dedicated units.
2Reliability
If a separate simmer power supply is used for each HVPT device, then each device has dedicated power, but the system cost increases
Solution Approach 1:
By merging multiple dedicated power supplies into a single shared unit, the overall system cost is reduced. The control circuit enables this shared power supply to reliably serve multiple devices through selective coupling, eliminating the need to purchase and install multiple expensive power supply units.
3Adaptability or versatility
If multiple simmer power supplies are used, then each device operates independently, but the system size increases
Solution Approach 1:
The patent merges multiple power supply units into a single compact shared power supply. The control circuit maintains device independence by selectively coupling the shared power supply to individual devices as needed, preserving operational independence while dramatically reducing system size.
Solution Approach 2:
The control circuit acts as an intermediary between the shared power supply and multiple HVPT devices. It manages the selective coupling, enabling devices to operate independently while sharing a common power source, thus reducing system size without sacrificing device independence.

AI summary
A power supply and circuitry system for powering HVPT devices includes a power supply circuit that selectively provides an operating power and a simmer power to multiple HVPT devices. The system also includes a trigger circuit for each respective HVPT device that selectively couples the power supply circuit to one HVPT device to provide the operating power thereto. The system also includes a simmer control circuit for selectively coupling the power supply circuit to the HVPT devices to provide the simmer power thereto, the simmer control circuit further including a simmer switch circuit for each HVPT device, wherein each simmer switch circuit comprises an input coupled to the power supply circuit to receive the simmer power therefrom and an output coupled to one HVPT device. The simmer control circuit also further includes a simmer drive circuit coupled to each simmer switch circuit for selectively enabling the simmer switch circuits.
