“…Voltage regulator module (VRM), as microprocessor power supply, requires a high step‐down converter with high output current [1, 2]. To reduce conduction losses in modern applications, usually a 12 V input voltage source is used which requires high step‐down conversion ratio of the converter [3, 4].…”

A zero voltage switching interleaved coupled inductor synchronous buck converter operating at discontinuous conduction mode (DCM)/continuous conduction mode (CCM) boundary condition is presented for step-down applications. To increase the duty cycle, coupled inductor structure with lossless clamp circuit is used. Moreover, operating at DCM/ CCM boundary has increased the efficiency by reducing the switching losses. However, this approach results in high output current ripple. To further reduce the input and output current ripple, interleaved structure is employed. Thus, high efficiency and low current ripple are the merits of the proposed converter which make it a proper choice for voltage regulator module applications. The operation of the proposed converter is analysed and design considerations are discussed. The experimental results obtained from an implemented prototype are provided to verify the theoretical analysis.
