Reference design aimed at e-bikes

Efficient Power Conversion (EPC) has developed an inverter reference design based around an integrated gallium nitride (GaN) chip that reduces the size of powertrains in electric bikes (writes Nick Flaherty). The design, for a 1.5 kW three phase brushless DC motor drive inverter, uses the EPC23101 eGaN chip. This has an embedded gate driver function […]

System-level approach to NVH models

Complex interactions between electric powertrain components provide significant challenges in accurately predicting the noise, vibration and harshness (NVH) performance of a design when using high level system-level models (writes Nick Flaherty). The models can help reduce the cost and development time, but the underlying interaction of the component-level simulations needs to be understood to achieve […]

Protecting electric ships with rapid DC switching

Potentially critical faults in the high-power DC powertrains increasingly found in ships, particularly ferries, must be isolated as quickly as possible to minimise damage and allow the rest of the system to continue operating as normal (writes Peter Donaldson). Key to this is the application of solid-state power electronics in the form of switches based […]

Battery Monitoring

Monitoring the performance of battery cells in a pack is pushing the limits of technology in many ways. Increasing the accuracy and reliability of the monitoring in the hostile environment of a battery pack, at voltages of more than 800 V and fluctuating temperatures, is a considerable challenge.
