Staggered phase pulse width modulated inverter apparatus

摘要: This disclosure describes an inverter utilizing semiconductor switching devices, such as transistors or gate controlled switches, in the legs of inverter. The are connected a bridge circuit and to source direct current. A filter network is between load across which alternating output be developed. devices gated on by application pulse width modulated signals having actual carrier frequency control electrodes various applied predetermined staggered phase relationship so that effective seen higher multiple frequency. Thus, need only out rather than lower frequency, while switched at high efficiency.
