至宝三鞭丸摘要：A method and apparatus for converting a direct current into an alternating current is disclod. The load is connected between a first and a cond load nodes and a source is connected between a first and a cond source nodes. The method involves producing a positive and negative half cycle of alternating current through the load. The positive half cycle is produced by causing a first and a cond switching control signals to effect a plurality of sub-cycles each comprising a first time period during which the first and cond switching signals are asrted and a cond time period during which the first and cond switching signals are not asrted. During each first time period of each sub-cycle, direct current flows from the first source node then through a first switch that conducts current from the first source node to a first intermediate node in respon to the first switching signal, then through a first inductor connected between the first intermediate node and the first load node, then through the load, then through a cond inductance connected between the cond load node and a cond intermediate node, and then through a cond switch that conducts current from the s
econd intermediate node to the cond source node in respon to the cond switching signal. During each
cond time period of each sub-cycle, a first shunt control signal is asrted to cau current to flow through a first unidirectional shunt from the cond intermediate node to the first intermediate node, then through the first inductor, then through the load node and then through the cond inductor back to the cond intermediate node. The negative half cycle is produced by causing a third and a fourth switching control signals to effect a plurality of sub-cycles each comprising a third time period during which the third and fourth switching signals are asrted and a fourth time period during which the third and fourth switching signals are not asrted. During the third time period in each sub-cycle, direct current flows from the first source node, then through a third switch that conducts current from the first source node to a third intermediate node in respon to the third switching signal, then through a third inductor connected between the third intermediate node and the cond load node, then through the load, then through a fourth inductance connected between the first load node and a fourth intermediate node, and then through a fourth switch that conducts current from the fourth intermediate node to the cond source node in respon to the fourth switching signal. During each fourth time period of each sub-cycle, a cond shunt control signal is asrted to cau
