An High Voltage Inverter IC may contain a six IGBT, 3 Phase Motor Bridge with level shift and Charge Pump circuit to drive an IGBT TOP Arm at up to 400VDC.Some Inverters contain 3 phase Stator Distribution logic, synchronized to Rotor position by Hall ICs and drive Brushless DC (BLDC) motors directly: these are called BLDC Motor Bridges. Other Inverters have six (6) inputs which the motor designer may use to drive AC Induction motors. Additional family members include Gate Drivers to drive larger motors using an external 3 phase Motor Bridge of IGBT or MOSFET devices. A key feature of all Hitachi Inverters is an ability to work directly at rectified line voltage in 110 and 220VAC power systems. However, in keeping with the system requirement of Motor Manufactures, All supply voltage between 10 and 400VDC are handled by this Inverter family.
For abbreviation purposes, this FAQs Document refer to both:
Motor Bridge and Gate Drivers as Inverters.
