Abstract: In a motor drive control system configured to include a converter capable of stepping up the voltage, when the locked state of motor generator 2 operating as an electric motor does not occur (NO in S 130), a voltage command value VHref for the converter output voltage is set according to respective required voltages of motor generator 1 operating as an electric generator and motor generator 2 (S140).  In contrast, when the locked state of motor generator 2 occurs (YES in S130), the voltage command value VHref is set to a limit voltage Vlmt or less for limiting the voltage step-up by the converter (S150, S180). When the locked state occurs, the converter output voltage is decreased and accordingly the DC voltage switched by the inverter is lowered, so that a switching loss at the switching device forming a part of the inverter is reduced and the temperature increase due to the heat generation can be suppressed.

Abstract: Topical compositions that may be useful for treating subjects with local inflammatory disorders such as pseudofolliculitis barbae, dermatitis, psoriasis, wounds, or sunburn are provided. Previously-known treatments have limited efficacy or require steroids that can cause undesirable side effects. Although NSAIDs have a safer profile, they are practically water insoluble and thus are typically formulated with alkanols or at low concentrations or both. The instant compositions taught here may be able to solubilize high concentrations of NSAIDs without high concentrations of alkanol and can contain water. Accordingly, such compositions may be capable of delivering therapeutic levels of an NSAID to targets in the skin.
