What Is The Difference Between A Solar Inverter And A Converter?
- Nov 01, 2017 -

What is the difference between solar inverter and converters? Solar inverter (inverter) is the DC power (battery, battery) into alternating current (usually 220v50HZ sine or square wave). Emergency power supply, the general is the DC battery into 220V AC.

Simply put, the solar inverter is an electronic device that converts low voltage (12 or 24 volts or 48 volts) of DC into 220 volts. Because we usually use 220 volts AC rectifier into DC, and the role of the inverter in contrast, hence the name. We are in a "mobile" era, mobile office, mobile communication, mobile leisure and entertainment. In the mobile state, people not only need to be supplied by the battery or battery low-voltage direct current, but also need us in the daily environment indispensable 220 volts AC, the solar inverter can meet our needs.

A converter is an electrical device that changes the voltage, frequency, number of phases, and other power or characteristics of the power supply system. Including rectifiers (AC variable DC), solar solar inverter (DC variable AC), AC converters and DC converters. In addition to the main circuit converter (respectively, rectifier circuit, solar inverter circuit, AC conversion circuit and DC conversion circuit), the need to control the power switching element on and off the trigger circuit and to achieve the power regulation, control of the control circuit. The trigger circuit of the converter includes the pulse generator and the pulse output device. The former according to the requirements of the control signal to produce a certain frequency, a certain width or a certain phase of the pulse; the latter will be the level of the pulse amplification for the converter in the power switch components required for the drive signal. Trigger circuit according to the control function can be divided into phased trigger circuit (for controllable rectifier, AC voltage regulator, direct down converter and active inverter), cut control trigger circuit and frequency control trigger circuit. The use of sine wave frequency control circuit can not only control the solar inverter output voltage, but also improve the output voltage quality. The control circuit of the converter divides the loop control circuit and the closed-loop control circuit according to the control way.

The former is mainly used in the requirements of some special equipment; the latter has the role of automatic control and regulation, widely used in a variety of work machinery. According to the nature of the control signal analog control circuit and digital control circuit. Analog signals are most commonly used in DC voltage and current, easy to use the power to be processed and transformed; digital signal is a set of information parameters with discrete values of the discontinuous change in the signal. Digital control with high precision, but the circuit is more complex and expensive. Therefore, in fact, widely used digital analog hybrid control circuit. In addition, the use of micro-computer control circuit also has many advantages.
