AC DC Converters

DC-AC converters, also known as inverters, transform direct current (DC) into alternating current (AC) to power electrical devices in both residential and commercial applications. In DC-AC conversion, the DC input is typically derived from batteries, solar arrays, or other direct current sources. DC-AC converters are used to enable AC-powered devices to be powered in off-grid situations. In order for DC-powered electronics to function in an AC-powered environment, a DC-AC converter must be used to convert the DC input into an AC output.

JWS60012 application field and working principle

The JWS60012 DC-AC converter is a three-phase voltage inverter designed for a wide variety of commercial applications. It is capable of providing 400V AC output at a frequency range of 45 Hz to 63 Hz, giving it the ability to convert DC or AC supplies to a respective AC or DC output. The device is equipped with an active current-regulation feature, which allows it to compensate for changes in AC signal waves, enabling it to maintain a consistent output. The JWS60012 offers high power efficiency and minimal power loss while providing a steady AC output.

JWS60012 DC-AC converter is designed for a wide range of applications, including powering electrical loads, electromechanical drive systems, and actuating electromechanical propulsion systems. It is suitable for powering motors, pumps, fans, compressors, and other devices requiring an AC signal, and for controlling the speed and torque of electric motors. It can also be used in applications such as medical devices, power control, and electrical power transmission.

The JWS60012 features a wide input range, allowing for the use of various types of AC or DC input supplies. It has a power capability of up to 600W at an efficiency of up to 98%. It also features strong protection from over-voltage, over-current, and over-temperature, as well as short-circuit protection and reverse-polarity protection. The device is also provided with safety monitoring and alarms, in order to indicate any faults in the power supply or in the load.

In terms of its working principle, the JWS60012 DC-AC converter utilizes four main operating stages. The first stage is the DC/AC conversion, in which the DC input voltage is transformed into an AC output. The second stage is the rectifier/filter stage, which filters the noise and admittance of the AC supply and regulates the amplitude of the AC voltage. The third stage is the switching stage, wherein high-frequency pulses are used to switch and adjust the output voltage. Finally, the fourth stage is the inverter stage, in which the switched output is transformed back into an AC output.

The overall working principle of the JWS60012 DC-AC converter is based on the operation of a voltage-driven switching network and a ground reference floating output. The device uses pulse width modulation (PWM) control to regulate the output voltage, providing a steady and clean AC output. The device is also equipped with a wide range of protection together with delay time control, which can be adjusted according to customer requirements.

The high-performance JWS60012 DC-AC converter is designed for reliable operation in a wide range of applications. Its active current-regulation feature enables it to maintain a steady output voltage, regardless of changes in AC signal wave, while its wide input voltage range and wide output range make it suitable for a variety of applications. Along with its protection and safety features, the JWS60012 provides users with an efficient and cost-effective way to convert DC or AC power into an AC output.
