ZF-BP Series IGBT High Voltage Variable Frequency Drive
The IGBT high-voltage drive developed by our company is a high-voltage variable frequency speed control device that uses insulated gate bipolar transistors (IGBT) as the core power device. It is widely used in the fields of power, metallurgy, petrochemicals, mining, municipal water supply, etc. We are committed to providing efficient and reliable variable frequency speed control solutions for high-voltage high-power motors.
Working Principle
Rectification process: Convert the input three-phase high-voltage AC power into DC power through a rectification circuit.
Inverter stage: Utilizing the high-frequency switching characteristics of IGBT, the DC power is inverted into three-phase AC power with adjustable frequency and voltage, driving the high-voltage motor.
Control link: Through digital controllers such as DSP or FPGA, precise control of IGBT is achieved, adjusting output frequency and voltage to meet motor speed regulation requirements.
FEATURES
Efficient and energy-saving: IGBT has low conduction loss and switching loss, and the inverter efficiency can reach over 96%, significantly reducing energy consumption.
High reliability: IGBT modules are designed in parallel or series, with high redundancy and low failure rate. It has protection functions such as overvoltage, undervoltage, overcurrent, overload, and overheating.
Wide voltage range: Strong adaptability to input voltage (such as 3kV-10kV), wide output frequency range (0-500Hz).
Modular design: The power unit, control unit, and drive unit are modularized for easy maintenance and expansion.
High power density: small size, light weight, saving installation space.
Technical advantages
High frequency switching technology: The switching frequency of IGBT can reach over 20kHz, with high output waveform quality and low harmonic content.
Soft switching technology: using zero voltage switching (ZVS) or zero current switching (ZCS) technology to reduce switching losses.
Multi level technology: By connecting multiple inverter units in series, the output voltage level is increased, dv/dt is reduced, and electromagnetic interference is minimized.
Digital control: Advanced control algorithms such as vector control and direct torque control are used to achieve high-precision speed regulation.
