Abstract
A rechargeable air-moving system (e.g., a hair drier, a pet groomer, a liquid sprayer, a vacuum cleaner, etc.) has a rather high voltage universal motor powered by a relatively low voltage rechargeable battery. The battery provides the benefits of portability and low-voltage safety, and the high voltage motor provides the benefits of speed, being lightweight and compact. In some examples, high voltage from a domestic AC power source is reduced to low voltage to charge the battery, and then a step-up converter increases the low DC voltage from the battery to a much higher voltage for the motor. The magnitude of the high voltage from the converter is comparable to the high voltage of the domestic AC power source. The relatively high voltage from the converter powers a high voltage universal motor that is lighter and more compact than a low voltage universal motor of equivalent power.
