Abstract

A fail-safe interface, to an inverter, the interface comprising a safe and reliable enable function is provided by way of discrete components with well-defined failure modes. The interface does not require complex circuits or architecture nor electro-mechanical devices that are inherently unreliable, have a short life expectancy, and are expensive. The safety-related components are contained in a single circuit comprising two independent channels. These channels are positioned either on a discrete circuit board together or for added resilience to failure, on one discrete circuit board per channel. Each channel comprises the safety-related parts for the fail-safe interface and is independently enabled and disabled. The reliable 'enable/disable function is provided by switch-mode converters.
