OZIP Intelligent Power Modules ship with one of three types of application firmware, DC/DC converter, active front-end/grid-tie inverter, or motor drive, as specified in the product model number.
Power StudioTM
Power Studio is a Windows-based GUI that can be used to easily configure and control the OZIP motor drive.
Motor Drive Firmware
The motor drive application firmware is designed for use with Oztek’s OZIP family of intelligent power modules. Intended for OEM applications, the OZIP-based motor drive solution provides high performance and efficiency at a fraction of the cost of a general-purpose industrial drive.
- Low distortion, sinusoidal drive waveforms
- Supports multiple control interfaces
- Open loop V/Hz control
- Closed-loop speed or torque control
- Induction and permanent magnet motor support
- Pre-charge and brake control
- CAN or Modbus RS-485 interface
- Easy setup via serial port with PC-based GUI
The drive can be configured for closed-loop speed or torque control using Field Oriented Control (FOC) for high-performance AC induction and permanent magnet motor applications. Open-loop V/Hz control is also provided for less demanding, low-cost AC induction motor applications.
A flexible control interface allows for analog, digital and serial interface options. High-voltage DC Link pre-charge control logic, as well as brake control logic, are provided for those applications that require them.
Control Modes
MODE
FEATURES
Open Loop V/Hz
Open-loop control for AC induction motors. This is the simplest mode to configure and can be used to control multiple motors in parallel.
Closed Loop Speed
Encoder-based, Field Oriented Control (FOC) for higher precision, more demanding AC induction as well as permanent magnet motor applications.
Closed Loop Torque
Encoder-based, Field Oriented Control (FOC) for direct torque control of AC induction as well as permanent magnet motors.
AFE-GTI Firmware
The AFE/GTI application firmware is designed for use with Oztek’s OZIP family of intelligent power modules. Intended for OEM applications, the OZIP-based AFE/GTI solution provides high performance and efficiency at a fraction of the cost of a packaged industrial solution.
- Low AC current harmonics – meets IEEE 519
- Improved power factor
- Active Front End (AFE) DC Link control mode
- Grid Tie Inverter (GTI) current control mode
- Grid Tie Inverter (GTI) power control mode
- Voltage boost capability
- Pre-charge control
- CAN or Modbus RS-485 interface
The inverter can be configured to operate in AFE or GTI mode. In AFE mode the inverter regulates the DC bus voltage and can be used to power a common bus or single-drive applications that require AC line regeneration and/or low harmonics. GTI mode is generally intended for renewable applications. In general, there is a separately-controlled DC source and the inverter is used to control real and reactive current or power to or from the grid.
DC/DC Firmware
The DC/DC application firmware is designed for use with Oztek’s OZIP family of intelligent power modules. Intended for OEM applications, the OZIP-based DC/DC solution provides high performance and efficiency at a fraction of the cost of a packaged industrial solution.
- Bi-directional buck/boost topology
- Low ripple interleaved implementation
- Current or voltage control modes
- Pre-charge control
- Easy setup via serial port with PC-based GUI
- CAN or Modbus RS-485 interface
The interleaved buck/boost converter is a bi-directional DC to DC converter topology that can be used to convert either a low DC voltage to a higher DC voltage, or vice versa.
By interleaving three converter legs with their modulators offset by 120°, the ripple current, and ripple voltage seen on the output, is significantly reduced due to the cancellation between phases. The bi-directional capability of the converter allows it to both source and sink current while regulating the output voltage.
