Abstract：
 The invention relates to a start power source used in the chain inverter of stable synchronous compensator, belonging to electric automatic device. The invention comprises an alternating current stabilizing power source, and N H-bridge inverter start power resources. Wherein, one alternating output of alternating current stabilizing power resource is through the central windows of all M current mutual inductors of said N H-bridge inverter start power resources, as the primary winding of M current mutual inductors, to returned to another output; the alternating current inputs of M single-phase full-bridge rectifiers are connected to the alternating current outputs of auxiliary windings of M current mutual inductors, while the positive and passive outputs of serially connected all direct current outputs are connected to the positive electrode and passive electrode of direct current capacitor of started H-bridge inverter; the M voltage-limit resistances are parallel connected to the alternating current inputs of M single-phase full-bridge rectifiers. The inventive start power resource uses the current mutual inductors to baffle the start power resource, and realize high insulation voltage resistance and lower part discharge, to reduce the cost of baffle circuit.
