DC DC Converters

VE-B1L-EW Application Field and Working Principle

DC-DC converters are used to transform the voltage of a source of direct current (DC) to a desired fixed or adjustable/stepped output voltage. In the case of VE-B1L-EW, the application field is to increase the voltage of a direct current source from 95V to 132V. The device mainly works by taking a DC input of 95V and converting it to an output of 132V with a conversion factor of 1.38.

VE-B1L-EW is a two-stage converter in which the first stage is an inverter which operates with pulse-width modulation (PWM). This is achieved by switching at a high frequency on/off electronic switches to generate pulse-width modulated voltage waves. The PWM peak voltage is kept constant while the integral value of all PWM pulses is adjusted. The two stages are then connected in series with the output of the first stage connected to the input of the second stage DC voltage booster. The output of the second stage is the desired 132V.

The PWM inverter stage of the VE-B1L-EW combines high performance power-switching technology and high-frequency pulse-width modulated (PWM) control. This method allows the device to increase the output voltage from 95V to up to 132V with a level of accuracy of 0.5%. The switching power diodes used are fast-recovery diodes with an operating temperature range between -20°C and 100°C. The use of fast-recovery diodes provides adequate protection against current inrush and overshoot.

The second stage in the VE-B1L-EW is the DC voltage booster, which utilizes the booster technique to raise the output voltage. This booster technique is used to convert a low-voltage DC input to a high-voltage DC output, by first charging the energy storage components of the circuit, then discharging it into the output circuit. This surge of energy gives a higher output voltage than the input.

The VE-B1L-EW also supports power supply sequencing, allowing for the power-on and power-off of multiple supplies in a specific order. This allows the user to safely and reliably power up/down systems that require multiple sources of power, such as a computer system.

In conclusion, VE-B1L-EW is a two-stage DC-DC converter which is able to convert a 95V DC input to an output voltage of 132V with a conversion factor of 1.38 using pulse-width modulation and the booster technique. It is a reliable and efficient device which offers the user a great degree of control and precision over the output voltage.
