“…Various timing difficulties can limit their maximum frequency to a value lower than that of true resonant circuits, and the boundary condition requirements for lossless switching are somewhat more restrictive than those for resonant pole converters. In many cases, however, these drawbacks are acceptable because of the benefit of low conduction loss and the elimination of switching loss [2].…”

Design Analysis of LCTLC Resonant Inverter for Two-Stage 2-Phase Supply System

Original scientific paperThis paper deals with the design analysis and synthesis of power resonant inverter with sinusoidal output voltage for sensitive loads. The proposed filter must be capable of removing higher harmonic components from the supplying voltage to reach a harmonic distortion of roughly 5% in the whole range of the load (0 − 100%). The inverter can be supplied from either single-phase voltage inverter in full-or half-bridge connection, or from simple DC/DC buck converter. Non-symmetrical control causes higher harmonic content, both odd and even. Simulation and experimental results based on designed parameters and subsequently obtained from Matlab and OrCad models confirm good quality of output quantities, voltage and current.Key words: DC/AC converters, LCLC resonant filter, resonant-mode power supplies, Bode diagram, Fourier analysis, transfer function Analiza dizajna LCLC rezonantnog invertera za dvostupanjsko dvofazno napajanje. Tema je ovogčlanka analiza dizajna i sinteza učinskog rezonantnog invertera sa sinisuidalnim izlaznim naponom za osjetljve terete. Predloženi filtar mora moći filtrirati više harmonike ulaznog napona kako bi distorzija harmonika bila oko 5% uči-tavom radnom području (0 − 100%). Inverter se može napajati ili iz jednofaznog naponskog invertera u mosnom ili polumosnom spoju ili iz jednostavog DC/DC buck pretvarača. Nesimetrično upravljanje uzrokuje pojavu viših harmonika u signalu, kako parnih tako i neparnih. Simulacijski i eksperimentalni rezultati temeljeni na sintetiziranim parametrima dobivenim od modela napravljenih u programskim paketima Matlab i OrCad potvr uju dobru kvalitetu izlaznih veličina napona i struje.

Abstract-This paper presents a reduction of ripple using π filter and c filter in bidirectional isolated dc-dc -dc converter. A typical application for this converter is battery charging for electrical vehicles, telecommunication and speed control of dc-motor. The advantages of the half bridge circuit with c filter are reduced ripple content present in the voltage and current waveforms, soft switching, low cost and high efficiency. The use of fuel cells is now envisaged to supply electrical energy in high power rail transportation application. The mat lab simulation results are compared with the experimental results.

“…Typical examples are the auxiliary resonant commutated pole (ARCP) (Bingen, 1985;McMurray, 1989;De Donker and Lyons, 1990), the ZVS (Barbi and Martins, 1991;Katsis et alii, 1997;Yuan and Barbi, 2000;Lai, 1997b;Pinheiro and Hey, 1996) and ZVT (Zero Voltage Transition) (Choi et alii, 2001) inverters. In these circuits, the auxiliary commutation circuit only helps main switches turn-on, while turn-off losses are reduced by snubber capacitors.…”

This paper proposes a new auxiliary commutation cell for PWM inverters that allows the main switches to be turned on and off at zero voltage and zero current. The main switches zero current turn-on reduces the undesired effects of parasitic inductances related to the circuit layout. The main diodes reverse recovery losses are minimized since di/dt and dv/dt are controlled. The ZCZVT commutation cell is located out of the main power path of the converters and is activated only during switching transitions. Additionally, the auxiliary switches are turned on and off at ZCS and use the same ground signals of the upper main switches. The commutation losses are practically reduced to zero. Soft switching operation is guaranteed for full load range without changes in command strategy. The operation of the ZCZVT PWM full-bridge DC-AC Converter is analyzed and an auxiliary commutation cell design procedure based on the analysis is proposed. Experimental results are presented to demonstrate the feasibility of the proposed commutation cell. RESUMOEste artigo propõe um novo circuito auxiliar para inversores PWM que permite que a entrada em condução e o bloqueio das chaves principais ocorram com corrente e tensão nulas. A entrada em condução das chaves principais com corrente nula reduz os efeitos indesejados referentesàs indutâncias intrínsecas do circuito. Uma vez que o circuito auxiliar controla o di/dt e o dv/dt, as perdas de recuperação reversa dos diodos principais são minimizadas. A célula de comutação ZCZVT, ativada somente durante as comutações,é localizada fora do caminho principal do fluxo de potência. Adicionalmente, as chaves auxiliares comutam em ZCS e usam o mesmo sinal de terra das chaves principais superiores. Devidò a ação do circuito auxiliar, as perdas de comutação são praticamente eliminadas. A operação com comutações suavesé garantida para toda a faixa de carga sem mudanças na estratégia de comando. A operação de um inversor ponte-completa ZCZVT PWMé analizada e, baseado nesta análise,é proposto um procedimento de projeto do circuito auxiliar. Para demonstrar a viabilidade do circuito de comutação proposto, são apresenta- dos resultados experimentais obtidos em um protótipo. PALAVRAS-CHAVE:Inversor, comutação suave, ZCZVT.
