Raztec and the 'Solar Fern'

Current transducers ensure energy management efficiency

A successful solar powered vehicle is the ultimate exercise in excellence in power management. Raztec Hall effect current transducers help New Zealand's challenger for the 'Panasonic World Solar Challenge'.

Energy management and conservation are critical for the performance of solar powered vehicles.

Energy flow is measured by monitoring voltage and current flow and Raztec Hall effect current transducers are ideal for the task of measuring the current flow as no loss is induced and readings are not disturbed by voltage in the current carrying conductor.

For example – the preferred way to control motor power is to operate under torque mode control. Depressing the accelerator pedal demands an increase in torque from the motor in proportion to the angle of depression. To ensure that this process works consistently, the torque controller must monitor motor current quickly and accurately and compare this with the demand from the accelerator - motor torque being directly proportional to current flow.

Because of their ability to perform reliably in critical applications, Raztec current transducers perform a splendid job of monitoring motor current resulting in large, easy to use signals with no inherent loss of energy.
