Rectifiers / Battery chargers


These devices can be designed with different technologies. The most important in the current market are the following:

Silicon Controlled Rectifier (SCR): is a type of thyristor made up of four layers of semiconductor material with PNPN or NPNP structure.

The thyristor term comes from a combination of “thyratron” and “transistor”.

This equipment is normally robust and with limited capacities.

Pulse width modulation (PWM): The PWM of a signal or power source is a technique in which the duty cycle of a periodic signal is modified (e.g. sinusoidal or square signal), either to transmit information through a communication channel or to control the amount of energy being sent to a load.

The rectifier is the essential component of any backup system that uses batteries and depending on its technology we can have different options available for control and monitoring.


EDCSUPPLY, as specialist in energy backup systems, focuses on the advice for the design and dimensioning of these equipment, besides the representation of leading brands in the market.
