... When PWM duty is extremely small, two or more switching elements cannot be driven entirely. In such case, switching elements will generate excess heat and it may cause destruction of the switching devices. Therefore, extensive heat evaluation is necessary for switching device selection particularly in consideration of the area of safety operation (ASO 16.WH 17.VH 18.UH 13.WL 14.VL 15.UL 12.ILIMIT NJM2625 Motor ...
