A seleção de varistores MOV para proteção contra surtos conforme a IEC 61000-4-5 exige dimensionamento baseado em energia, escolha correta do diâmetro do disco e posicionamento adequado na entrada de alimentação. Este guia aborda corrente de surto, tensão de clamping e arquitetura de proteção em camadas para sistemas CA.
Seleção de varistor MOV para proteção contra surtos em entrada de energia CA conforme IEC 61000-4-5
Sistemas de alimentação que passam em testes funcionais frequentemente falham durante a validação de surtos IEC 61000-4-5. Os sintomas incluem reset do controlador, perda de comunicação e travamento da fonte, indicando capacidade insuficiente de absorção de energia ou posicionamento incorreto do MOV.
Características do Surto
A IEC 61000-4-5 define uma forma de onda combinada com tensão de 1,2/50 µs em circuito aberto e corrente de 8/20 µs em curto-circuito. Essa condição apresenta energia significativamente maior que ESD e requer seleção baseada em corrente de pico e energia absorvida.
Os varistores MOV das séries TSV e TSVG cobrem tensões de 18 V a 1800 V e suportam correntes de pico elevadas de acordo com o diâmetro do disco.
Falhas Comuns de Projeto com MOV
Disco subdimensionado provoca estresse térmico em surtos repetitivos. Tensão nominal muito próxima ao valor RMS causa corrente de fuga contínua. Proteção em estágio único aumenta a tensão residual. Trilhas longas aumentam overshoot por indutância parasita.

Discos maiores aumentam a corrente de pico e a energia suportada, porém elevam a capacitância e o espaço ocupado na PCB.
Seleção Orientada por Parâmetros
Determinar a tensão RMS máxima da rede. Identificar o nível de surto linha-linha e linha-terra. Calcular a corrente de pico 8/20 µs. Selecionar o disco com margem de energia. Verificar a tensão de clamping em relação aos componentes a jusante.
Considerações Térmicas e Vida Útil
A degradação do MOV é cumulativa. Cada surto aumenta a corrente de fuga e altera a tensão do varistor. O projeto deve considerar espaçamento térmico e evitar operação próxima ao limite de tensão contínua.
Estratégia de Posicionamento
Posicionar o MOV na entrada de energia com trilhas curtas. Instalar entre fase e neutro para proteção diferencial. Adicionar MOV fase-terra conforme a categoria de surto.
Arquitetura de Proteção em Camadas
O MOV absorve alta energia, porém a tensão residual pode exigir um clamp secundário no barramento DC e um choke de modo comum para reduzir o estresse nos circuitos de controle.
Exemplo de Aplicação AC-DC
Entrada 230 VCA com requisito de surto de 1 kV linha-linha e 2 kV linha-terra. Utilizar MOV 14D entre fase e neutro com impedância em série antes da ponte retificadora. Verificar a tensão no barramento DC durante o surto.
Método de Verificação
Medir a tensão de clamping no barramento DC. Monitorar a temperatura do MOV em surtos repetitivos. Verificar corrente de fuga após testes. Validar recuperação funcional do sistema.
Parâmetros Necessários
Tensão RMS CA e tolerância. Nível de surto e modo de acoplamento. Forma de onda de corrente de pico. Número de pulsos. Tensão máxima de clamping. Espaço disponível na PCB.
Conclusão
A conformidade com a IEC 61000-4-5 requer seleção de MOV baseada em energia, corrente de pico, diâmetro do disco e posicionamento adequado. A proteção coordenada reduz o estresse residual e aumenta a confiabilidade do sistema.

Ripple current failure in electrolytic capacitors originates from internal heating caused by AC ripple superimposed on DC bias. Ripple heating accelerates electrolyte evaporation, increases ESR drift, and reduces effective capacitance. When internal heating combines with elevated ambient temperature, service life decreases faster than predictions based only on rated voltage or ambient rating.
System-Level Reliability Issue in SMPS and LED Drivers
Radial aluminum electrolytic capacitors in output filters experience continuous ripple stress. In SMPS topologies operating above 50kHz, RMS ripple current can exceed thermal design assumptions. In LED drivers, enclosed fixtures create high ambient conditions, further elevating capacitor core temperature.
Typical field symptoms include ESR rise, capacitance drop, ripple voltage increase, LED flicker, and output instability. These failures are thermal wear-out mechanisms rather than dielectric breakdown.
Electrothermal Mechanism of Ripple Heating
P = Iripple2 × ESR
Ripple current generates heat internally in the electrolyte and foil structure. Poor thermal dissipation causes localized temperature rise. Elevated core temperature accelerates electrolyte loss and oxide layer degradation, increasing ESR, which in turn increases ripple heating in a feedback loop.
Lifetime Impact Under Combined Stress
Temperature acceleration models show lifetime approximately halves for every 10°C rise. Ripple-induced core heating adds to ambient temperature, effectively pushing capacitors toward their endurance limits. Continuous operation environments such as LED luminaires and industrial power supplies show highest vulnerability.
