单相交流电压转换器具有以下详细信息-
开启时间= 6分钟,关闭时间= 4分钟,频率= 50Hz,并且
电压源V o = 110V
计算以下内容。
解决方案–
$ T = 2 \ times \ left(T_ {ON} + T_ {OFF} \ right)$但是$ f = 50Hz,$ $ T = 2 \ times \ left(6 + 4 \ right)= 20mins $
$ 360 ^ {\ circ} = 20min,$ $ 1min = 18 ^ {\ circ} $
因此,$ T_ {OFF} = 4min $
然后,
$$ \ alpha = \分数{4} {0.1} \时间1.8 = 72 ^ {\ circ} $$
解决方案–
$$ V_ {0} = \左(V_ {S} \ times D \ right),\ quad其中\ quad D = \ frac {T_ {ON}} {T_ {ON} + T_ {OFF}} = \ frac {6} {10} = 0.6 $$ $$ T_ {ON} = 6min,\ quad T_ {OFF} = 4 min,\ quad V_ {S} = 110V $$ $$ V_ {0} \ left(电压输出\ right)= V_ {S} \ times D = 110 \ times 0.6 = 66Volts $$
