VE-J4L-MZ-F4

The VE-J4L-MZ-F4 is a DC/DC converter belonging to the current-fed phase shifted full bridge converter family. It is designed to reduce incoming voltage to a regulated DC level and allows very high efficiency and small package size. The VE-J4L-MZ-F4 converter is suitable for a variety of power sources such as photovoltaic modules as well as grid power. It can also be used for other applications such as industrial robotics, LED lighting, metered power systems, and other applications requiring a regulated DC input.

The VE-J4L-MZ-F4 includes a full bridge rectifier and an adjustable switching frequency DC/DC converter. The full bridge rectifier converts the incoming AC voltage to a DC voltage. The DC output is then fed into the DC/DC converter, where it is regulated to the desired voltage in a high efficiency manner using Pulse Width Modulation (PWM). The adjustable switching frequency enables the VE-J4L-MZ-F4 to regulate the output voltage with minimal ripple over a wide range of input voltage.

The key features of the VE-J4L-MZ-F4 DC/DC converter include high efficiency up to 88%, high switching frequency up to 500kHz, low power dissipation down to 1W, precise output voltage and current regulation as low as ±0.5%, and a wide input voltage range, from 160V to 600V. Additionally, the VE-J4L-MZ-F4 has a wide operating temperature range from -40°C to +105°C and robust protection against over-current, over-voltage, short circuit, and thermal shutdown. Moreover, the VE-J4L-MZ-F4 includes a wide variety of features and options such as Power Factor Correction (PFC), Over-Voltage Protection (OVP), active input disconnection, and passive inrush control.

The current-fed phase shifted full bridge converter topology is ideal for applications that require high power density and efficiency, and the VE-J4L-MZ-F4 excels in this regard. The converter uses four power switches (or two if a semi-bridge configuration is used) to convert high voltage AC power to low voltage DC power with high efficiency, making it suitable for a wide variety of energy-efficient applications. With its adjustable switching frequency, the VE-J4L-MZ-F4 is especially useful for applications that require constant voltage and/or constant current regulation. Additionally, the VE-J4L-MZ-F4’s low ripple reduces noise for sensitive applications.

In summary, the VE-J4L-MZ-F4 is a high efficiency, high power density DC/DC converter with a variety of features and options. It excels in applications that require constant voltage and/or constant current regulation, and its adjustable switching frequency allows for minimal ripple for a wide range of input voltage. Additionally, its low power dissipation and wide operating temperature range make it suitable for a variety of energy-efficient and harsh environment applications.
