AC DC converters are widely used in many industries, with a variety of voltage configurations, resonance structures, and control topologies. One such converter is the VOF-85-5 application field and working principle.

The VOF-85-5 is an asynchronous pulse-width modulation (PWM) Voltage Source Inverter (VSI) designed to drive three-phase AC induction motors, particularly in reactor-based industrial process control applications. It is a full bridge, three phase inversion control. Comparisons of such devices are typically made based on converter weight and power factor (PF) as well as zero cross comparison.

The VOF-85-5 is designed to conveniently configure the required voltage and switch frequency for an operation within its application field. It also offers an optional variable switching frequency for better motor speed control. This makes it the perfect choice for many applications as it offers enhanced motor speed regulation without compromising the efficiency of operation.

The VOF-85-5 is an adjustable frequency inverter that can operate in either open loop or closed loop on motor velocity or torque demand. It is a voltage source inverter and functions by controlling the voltage and frequency applied to the motor’s windings, which in turn controls the speed and torque of the motor. This makes it suitable for applications where smooth torque control is required.

Due to its adjustable switching frequency, the VOF-85-5 offers variable motor speed control and adjustable gains, for maximum performance efficiency in various applications. It works on the theory of pulse carrier modulation (PCM). A carrier signal is generated at a certain frequency, which is multiplied by the modulating signal (or voltage) to produce the output waveform. The output wave is compared with the feedback signal to maintain the voltage regulation of the load.

The VOF-85-5 utilizes a sophisticated bridge switching mechanism to ensure a clean cutoff and low EMI. It offers superior efficiency and high current capability as well as the ability to operate over a wide range of temperatures. It is also designed for harsh environmental operating conditions such as desert regions.

The VOF-85-5 provides an effective solution for a wide variety of applications from medical and laboratory equipment to industrial applications such as compressors and pumps. It is a durable and stable unit that offers reliable operation. In conclusion, the VOF-85-5 is an efficient and cost effective AC/DC converter designed to deliver superior performance for a variety of applications.
