ZERO VOLTAGE SWITCHING FULL BRIDGE CONTROLLERS MARKET

INTRODUCTION

 When the immediate voltage is zero, ZVS (Zero Voltage Switching) refers to switching the 110/230VAC output. Compared to ZCS, ZVS (Zero Voltage Switching) is simpler to accomplish (Zero Current Switching).

Devices like switching power supply can be turned on and off using ZVS. One of the frequently employed types that provides isolation in addition to stepping up or down the input voltage is a full bridge converter.

Other capabilities might include switching the polarity and delivering numerous output voltages at once. There are three main steps in a bridge converter: the generator of square waves.

ZERO VOLTAGE SWITCHING FULL BRIDGE CONTROLLERS MARKET SIZE AND FORECAST

The global zero voltage switching full bridge controllers market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.

ZERO VOLTAGE SWITCHING FULL BRIDGE CONTROLLERS MARKETNEW PRODUCT LAUNCH

The XDPS21081 from Infineon is a flyback controller IC featuring a full bridge converter with ZVS (zero-voltage switching) on the primary side to achieve great efficiency with condensed circuitry and low-cost switches.

In comparison to conventional valley switching type of switching methods, switching losses can be further decreased by using an external low voltage switch to create a negative current to discharge the primary high voltage MOSFET.

The XDPS21081 multi-mode digital forced quasi-resonant (FQR) flyback controller IC assures DCM (discontinued conduction mode) operation via valley detection for a secure and reliable operation in order to achieve high efficiency with synchronous rectification.

advantages are high switching frequency and high density, High efficiency with variable output design, adaptive ZVS operation, and frequency law SR operating with DCM operation is secure and reliable. Dual integrated gate drivers and a start-up cell make design simple. Configurable design is made simple with GUI tools.

 Renesas manufactures Zero Voltage Switching (ZVS) Full Bridge Controllers. The alternative zero voltage switching (ZVS) full bridge pulse width modulating (PWM) controllers with great performance and minimal pin count make up the ISL675x family of controllers.

These components operate in ZVS mode by driving the lower bridge FETS with configurable resonant switching delays and the upper bridge FETS with a fixed 50% duty cycle. Applications include ZVS full bridge converters, wireless base stations, file servers, telecom and datacom power, and industrial power systems.

ZERO VOLTAGE SWITCHING FULL BRIDGE CONTROLLERS MARKETRECENT DEVELOPMENT

The development and implementation of a full bridge phase shift pulse width modulation converter with high power, high voltage, constant frequency, and zero voltage switching of all active switches throughout the whole load range are described.

Two capacitors are utilised as auxiliary circuit components in series across the DC power rail, and two inductors are used in series with the converter's transformer.

The two inductors provide additional current to reinforce the primary current during transition intervals and increase the energy available to achieve the zero voltage switching, while the two capacitors serve as a voltage divider to provide halfway voltage source (ZVS).

Based on this topology, a prototype converter is developed that produces 450V @ 5 kW output from 560V dc input with an efficiency of over 94%. Results from simulations and experiments are reported for the converter. 

Full bridge phase shift pulse width modulation (FB-PSPWM) converters are frequently used in medium- to high-power DC-DC converter applications due to their fixed switching frequency ZVS operation, high efficiency, low EMI, relatively low circulating energy, utilisation of output parasitic capacitance of the switches, and utilisation of leakage inductance of the transformer.

The fundamental problem of the standard FB-PSPWM converter, however, is the constrained operating range within which the ZVS may be performed. In the traditional FB-PSPWM converter, the energy stored in the transformer's leakage inductance mostly determines the ZVS of the left leg switches. 

Loss of ZVS state results from insufficient energy being stored in the transformer's leakage inductance to charge or discharge the switch capacitances when the load is low. Using an additional LCC circuit with a standard FB-PSPWM DC-DC converter is another approach for achieving a wider ZVS range.

A voltage divider and an inductor are connected between the middle point of a voltage capacitor divider and the middle point of the left leg of a traditional FB-PSPWM converter to form the auxiliary circuit. When compared to the left leg switches, the right leg switches depart ZVS with a lighter load.

To reduce turn-on losses, especially those caused by a lack of load, ZVS is preferred for both legs. If one more inductor is employed in addition to the LCC circuitry, it is suggested that the ZVS for both legs of the FB-PSPWM DC-DC converter can be obtained.
