Constant-frequency parallel-resonant converter (clamped-mode)
A steady-state analysis of a Constant-Frequency Parallel-Resonant Converter operating in the Clamped-Mode is performed for the continuous-conduction mode of operation (CCM). Unified closed-form expressions are derived for such circuit characteristics as the control to output, boundary conditions …

Computer simulations for constant-frequency resonant power processors
Simulations of two types of constant-frequency resonant power converters using SPICE-2/I-G SPICE are performed. The first one is a parallel resonant converter (PRC) using a controlled output rectifier. The PRC is operated at a constant frequency and its output voltage is regulated by controlling …

Digital Control of a High Frequency Parallel Resonant DC-DC Converter
A brief analysis of the nonresonant-coupled parallel resonant converter is performed. The converter is modeled and a reference classical analog controller is designed and simulated. Infrastructure required for digital control of the converter (including anti-aliasing filters and a modulator) is …

Constant-frequency resonant power processors
Two constant-frequency resonant power processors are discussed. The parallel resonant converter(PRC) with a controlled output rectifier can provide both forward and reverse power flow. A new control parameter — "θ-angle" is proposed for achieving output regulation and bidirectional power flow of …

Constant-frequency, clamped-mode resonant converters
Two novel clamped-mode resonant converters are analyzed. These clamped-mode converters operate at a constant frequency while retaining many desired features of conventional resonant converters such as fast responses, zero-voltage turn-on or zero-current turn-off, and low EMI levels, etc. The …
