摘要： PURPOSE:To prevent a system from stopping by providing a limiter to an invertor to make rated operation simultaneously when the output of a self-excited invertor reaches rating, and returning the limiter when it reaches within the rating. CONSTITUTION:The output of an invertor 1 is normally detected by a KVA detection section 5, and it is compared with the rating KVA of the invertor by a comparator 6. When the detection KVA of the detection section 5 is smaller than the rating KVA, the comparator 6 does not energize hold circuits 7 and 8, and the outputs of an effective power control ampere 3 and reactive power control ampere 4 are transmitted to a gate control section 9 as they are to control the invertor 1 in accordance with the load. When the detection KVA of the detection section 5 is larger than the rating of the invertor, in that moment the comparator 6 outputs to energize the hold circuits 7 and 8, and the outputs of the effective and reactive power control amperes 3 and 4 are limited to control the gate control section 9. When the output returns within the rating, the limit is released. According to the constitution, the rated operation is continued without stopping the operation.

摘要： PURPOSE:To prevent the erroneous operation of control by eliminating to energize a main power source in the state that a control power source of a controller which controls an inverter is not established. CONSTITUTION:When a breaker contact MCB2 is closed, a sub smoothing condenser 12S is precharged by the DC output of a rectifier 18S through a current limiting resistor R. At this time a power source voltage is not applied to an inverter 14 by the operation of a diode D which is connected in series with the condenser 12S. The terminal voltage of the condenser 12S is converted by a DC/AC converter 20 into an AC, which is supplied to a controller 22 through a transformer Tf1. When the control power source reaches the prescribed value, the contact MC is closed by an instruction signal, a main smoothing condenser 12M is precharged, a novoltage detecting coil is energized by the instruction signal which is obtained through a transformer Tf2, and a breaker MCB1 is closed.
