  • Page 41: General Description Of The Inverter 3

    Inverter Theory of Operation This section describes the theory of operation of the Topaz S3 Inverter systems. The inverter utilizes a "Fly-back" converter to boost the input voltage to two regulated +/- 200 volt outputs. Two identical inverters are contained in the unit, both inverters controlled by a single PWM to generate sinusoidal AC outputs.

  • Page 43 3.1.1 Battery Booster 3.1.1.1 Hysteretic Booster Operation 86-153061-00 The battery booster is a "continuous" mode Fly-back converter which takes the DC input voltage and boost it to four separate outputs of 200 volts. Two of these outputs are connected in series to produce -200 VDC and +200 VDC and used by one of the Inverters.
