How do Phase Converters Work
Read on to know more about the different types of phase converters and how they work.
A phase converter is a device that converts the power from a singe phase source into 3 phase power.
Phase converters were invented in the later part of the 1900s. They are also known as 3 phase converters. The first phase converters were static in nature. Later development gave rise to the rotary phase converters, and recently, we see the digital variants in use.
Uses
Phase converters find their applications in places where there is only a single phase power source for running various applications which require 3 phase power. Normally, 3 phase power is very costly, and it is often not supplied in all the areas. Therefore, these phase converters are quite useful for converting the power in such areas.
Types
Static Phase Converters
These are the simplest type of phase converters. They contain one or more capacitors and a relay. The relay switches between the capacitors once the motor comes to speed.
Static phase converters run under the principle that a 3 phase motor can be started by using the capacitors in a series via the third terminal of the motor. They, however, can run for only short periods of time or they end up delivering only half output, else they become damaged with overheating. Thus, they can only operate single load motors for a short period of time.
Rotary Phase Converters
A rotary phase converter contains a bank of capacitors wired together to act as one big capacitor and a 3 phase motor. 2 leads to the motor are connected to the single phase power source. The third lead is connected to the capacitor in series. Normally the motor used is larger than the load it supplies.
For loads that need more balanced voltage in the output, the size of the frame of the converter motor is normally increased.
Rotary phase converters can provide resistive, capacitive, and inductive loads and they can power several loads at one time. They have a simple design and are reliable and low on cost. However, the only problem is in maintaining a voltage balance. To combat that problem, motors of a larger size are used only for a single machine each. Thus, rotary phase converters are an effective solution for simple load motors.
