This invention relates to a switched-mode drive circuit and method for an inductive component. The invention more particularly, but not exclusively, relates to buck, boost and push-pull drive circuits.

Drive circuits comprising a first switch having first and second terminals, a second switch...

This invention relates to a drive circuit and the method for driving a transformer. More particularly the invention relates to a drive circuit and method for driving a transformer which forms part of an ignition system for an internal combustion engine.

In order to improve emissions in petrol...

This invention relates to an ignition system for an internal combustion engine and a method of driving an ignition plug of an ignition system.

In order to improve emissions in petrol internal combustion engines to meet emission standards, the engine needs to be operated with a high exhaust gas...

This invention relates to an ignition plug for an internal combustion engine.

In order to improve emissions in petrol internal combustion engines, the engine may be operated with exhaust gas recirculation (EGR) or lean air- fuel mixtures. However, combustion stability may become unacceptable...

A cost-effective tip appendage design that reduces tip leakage vortices in axial flow fans to improve fan performance. The appendage is robust in that it is applicable to various axial flow fan designs and can be installed on currently operational units through retrofitting due to its simplistic...

This invention relates to a system that continuously measures and monitors the dynamic behavior of turbomachine blades in order to provide early warning of incipient blade failure. This would enable management to take corrective action in order to prevent failure and downtime. The system be used in...

This technology uses Unmanned Aerial Vehicles (UAVs) fitted with a camera to calibrate heliostats in large Concentrating Solar Power (CSP) or Concentrating Solar Thermal (CST) tower systems. The UAV does not have a single fixed position and provides several advantages over traditional methods...

Power plant efficiency is generally determined by projected electricity tariffs and power plant life cycle costs during the design phase. This technology can be installed below wet cooling tower fills to significantly enhance the thermal performance of the cooling towers, resulting in a reduction in...

A cost-effective, highly efficacious trough assembly for collecting and removing drops with minimal air-side pressure drops for use in evaporative heat exchangers or cooling towers. The innovation reduces water consumption and required fan power. The elimination of a rain zone reduces the...
