Functional description of the modulator
The modulator consists of:
• A network voltage rectifier, followed by a filter capacitor giving a fixed direct voltage which depends on the network voltage.
• An inverter: this direct voltage powers the 6-transistor inverter (IGBT). The inverter converts direct voltage into voltage and frequency modulated alternating voltage.
• Three internal current measurements for the DC bus, the inverter output and the braking transistor.
• An electronic control card. comprising: the microprocessor, the PWM generator ASIC circuit (PWM) and the power control signal amplification circuits.
• An operator panel allowing configuration, reading information and controlling the modulator.
FMV 2107: general-purpose frequency modulator and 200V/240V single-phase power supply.
FMV 2307: general purpose frequency modulator and three-phase power supply
1.5 = Rating in kVA. M = Single-phase power supply. TL = 200V/240V three-phase power supply. T = 380V/480V three-phase power supply.
