Abstract
PURPOSE:To economically manufacture an inverter which is supplied with high- voltage DC power, by substituting a series circuit of capacitors of equal capacity for a filter capacitor, using the series circuit also as a voltage dividing circuit and using commercially mass-produced transistors. CONSTITUTION:The DC input sides of a plurality of transistor inverters 1-3 are connected in series with one another and coupled to a high-voltage DC power source across an intermediate circuit comprising a filter reactor L and filter capacitors C1-C3. The filter capacitors are voltage dividing capacitors corresponding to the transistor inverters and connected across the DC input terminals of the corresponding inverters. The voltage dividing number is selected so appropriate that an inverter circuit is formed without connecting transistors in series with one another. For this reason, the inverters which are applied with high-voltage DC power for an electric railroad or the like can be economically manufactured from commercially mass-produced transistors.
