UFC762AE101 3BHE006412R0101 ABB Processor Module

Description

ABB UFC762AE101 3BHE006412R0101 Inverter circuit board

A three-phase inverter with a continuous power rating of 1.25kW at an ambient temperature of 50°C and 550W at 85°C is used to drive a 200V AC servo motor. It features a 600V LMG3411R150 gallium nitride (GaN) power module and has an integrated FET and gate driver mounted on a 1.95mm insulated metal substrate (IMS) for efficient heat dissipation. The isolation and control circuits are mounted on separate FR-4 boards - the dimensions of the design are 80mm x 46mm x 37mm and include the heat sink, control circuit, isolation circuit and power stage. With natural convection fanless cooling, this ultra-small form factor allows easy integration of the drive with the motor, reducing the cabinet space required for 6-axis motor applications including robots, CNC machines, etc., by up to 50% and reducing cable length by 90m.

peculiarity

• The 600V, 6A LMG3411R150 GaN enables power densities up to 150 W/in3 at ambient temperatures of 50°C and power up to 1.25kW, and at ambient temperatures of 85°C and power up to 550W

• Ultra-small form factor and natural convection fanless cooling make it easy to integrate the drive with the motor, saving floor space and cabling costs

• The switching is very fast (< 5ns) and the switching node voltage ringing is very small, thus reducing EMI

• High efficiency power stage (peak efficiency >99% at 32kHz PWM) to reduce radiator size

• Provides protection against gate undervoltage, device overcurrent and overheating

Basic principle of inverter power supply

1.1 Half bridge inverter circuit

There are many ways to obtain AC power from DC power supply, but at least two power switching devices are required, and the half-bridge inverter circuit is a topology of the single-phase inverter power supply. The circuit consists of two power switches in series and two capacitors in series. The midpoint of the two series capacitors is the reference point. The circuit works as follows: when V1 is on and V2 is off, the energy on the capacitor C1 is released to the load R, the output voltage Uo is positive, and the capacitor C2 is charged at the same time; When V1 is turned off V2 is on, the energy on the capacitor C2 is released to the load R, the output voltage Uo is negative, and the capacitor C1 is charged. The switching tube V1 and V2 are switched on alternately so that the load can obtain AC power.

The advantage of the half-bridge inverter circuit is that the circuit structure is simple, and the series center of the two capacitors is used as a neutral reference point, which will not bring DC component and magnetic bias, and is suitable for driving the transformer load. The disadvantage is that when the circuit works at the power frequency (50Hz-60Hz), the capacity of the required capacitance is relatively large, increasing the volume and cost of the circuit.

1.2 Full-bridge inverter circuit

The full-bridge inverter circuit is the most widely used circuit in college students' electronic design competition. Single-phase full-bridge inverter circuit describes the basic principle of full-bridge inverter circuit. The single-phase full-bridge inverter circuit is also known as the 'H-bridge' circuit, which is composed of four power switching tubes and their driving auxiliary circuits. Q1 and Q4 complement each other on and off when working, and Q2 and Q3 complement each other on and off. When Q1 and Q3 are closed and Q2 and Q4 are disconnected, the load voltage Uo is positive; When Q1 and Q3 are off and Q2 and Q4 are off, the load voltage Uo is negative, and the Uo waveform is shown in Figure 2(b). Q1, Q3, Q2 and Q4 are switched on alternately, so that AC power is obtained on the load. When the load is not pure resistance, the load voltage and load current are not in phase, then the parasitic diode D1-D4 of the switching tube plays the role of current continuation.
