In　this　paper,　we　investigate　the　effect　of　multiple　delays　on　the　3-D　simple　chaotic　system　with　hidden　chaotic　attractors　coexisting　with　one　stable　equilibrium　by　Wang　and　Chen.　In　order　to　investigate　complex　dynamics　of　hidden　chaotic　attractors　with　multiple　delays,　we　choose　and　as　bifurcating　parameters　and　consider　the　stability　of　equilibrium　and　the　existence　of　Hopf　bifurcations.　Some　explicit　formulas　for　determining　the　direction　of　bifurcations　and　the　stability　of　bifurcating　periodic　solutions　are　obtained　by　using　normal　form　theory　and　center　manifold　theory.　The　numerical　simulations　are　performed　to　support　the　correctness　and　effectiveness　of　the　analytical　results.　The　effect　of　multiple　delays　can　be　applied　to　the　chaotic　system　only　with　one　stable　node-foci　for　the　purpose　of　control　and　anti-control　of　hidden　chaos　by　delayed　switchover.　Furthermore,　to　reach　deep　and　clear　understanding　of　the　dynamics　of　such　hidden　attractors,　circuit　implementation　of　the　multiple　time-delay　system　is　analyzed　using　the　PSpice.
