Smartboy Power Converters

From the so-called advertisement Smartboy power converter:

We face the problem of high energy consumption almost every day, including every day TV, household appliances, computers and other devices. By itself, each device takes a little, for example, a refrigerator from 150 to 1500 VA, fluorescent lamps - 12-500 VA, washing machine - 300-700 VA, etc. And counting everything together, it comes out to a tidy sum that grieves us every month.
The smart boy is designed to help users. Typically, all models of Smart Boy energy converters consist of five modules that work together, resulting in energy savings: control with a programmable controller or multi-level transformer, overvoltage protection, active filtering, power factor correction, phase compensation.

All elements of the device operate in a wide frequency range from 30 to 100 Hz inclusive.An important element that technically implements the saving process is realized by semiconductor high-speed proximity switches controlled by the sensor command for the angle of change between current and voltage in each phase of the electrical load. If the sign of the voltage and current phases coincide, the switch transmits active electrical power to the load from the network, if not, the electronic switch connects the reactive current to the phase of the load in which it is currently required. In this way, the non-contact regulator performs an even start of the electrical load when starting the electric motors, providing thermal protection and maximum current protection of the equipment.

Smart Boy's energy saving is able to simultaneously eliminate higher harmonic currents in the wires, suppress network noise and at the same time maintain the working state of the network during short-term overloads.
Buying a miracle device, the energy savings will pleasantly surprise you — it will be up to 30%. It also extends the life of household and industrial appliances. Easy to operate, does not take up much space. There is no need for constant repair and maintenance.
In terms of power, there are two types: 19 kW — for home use (family of 3-4 people) and 45-120 kW — for enterprises.

Our review: Large businesses with equipment with a large inductive component pay for reactive energy that loads power lines and is not profitable for the same electricity supplier.

To relieve power lines from additional load, there are special reactive power compensators (industrial).They are synchronous motors operating in overexcitation mode or static capacitor banks with automatic or manual control system.

These are bulky and complex devices designed for specific equipment. True compensators have a sophisticated control and monitoring system that allows you to adjust the amount of compensation required, depending on the load at any given time. Smart Boy energy saving, despite all the described advantages, is a common means of fraud and extortion of money from customers.
